Hey guys
i have a vz ss 6l. its just finished having a gen t singal turbo kit fitted an was sent off to the tuners on tuesday.. The car has a in tank walbro pump (for now) , 60lb siemens injectors , valve springs , the turbo is a Garret gt 35/40, 3inch hiflow cats an 3inch di fillipo catback.. when the car was n/a with a OTR 1 7/8 di fillipos 3inch hiflow cats an 3inch di fillipo catback it was apparently makeing 270rwk. the cars a manual to, anyway the tuners reackon it made 304rwk dose that sound right??? when iv heard of gen 3's maken 340rwk + with pritty much same set up.. would love to hear your thoughts..... i forgot to say that cars running 7psi boost at the moment an besides valve springs the motor is stock...
cheers.......

A safe tune running 7psi soulds about right, considering it has a walbro in tank pump, not that there is anything wrong with them.
A bigger fuel system 12psi and a re-tune would be interesting, I would imagine then you would see 340rwkw's
do you have a dyno graph for before and after, 270 for a stock ls1 with just df and otr sounds just doable

Hey mate its not a ls1 its a l98 6L vz nahh i carnt find the dyno sheet when it had the mafless tune done it was ages ago but apparently it was maken 270 after the mafless tune OTR an exhaust but i dunno if i beleave that thay hadnt finish tuneing it they called me today they had problems with the injectors the o rings were leaking fuel when it was coming on high boost so there gunna fix em and finish it tomorrow but he said it was maken 304rwk at the moment and he sounded happy with that i just thought a 6l would of made a little bit more but ahh welll it is what it is i spose

It should be making way more then 304rwkw with boost. That is cam only territory for the 6Ltr's.

hey mate thanks for the comment i know thats what i was thinking why did i spend all that money on a turbo kit when i could of done a cam for half the price and made more power it just dosnt seem right. im a littel dissapointed the motor only done 50,000ks to so its only just run in lol

why did you go the GEN T I would have thought the 35/40 would be a bit small for a 6L
they run out of puff on LS1's at around 5000rpm

its running 7psi boost would more boost an bigger fuel system help???

Wouldn't hurt, but a decent size turbo and a fuel system would be a better idea.

I agree, personally I would be looking at something bigger then GT 35/40 as a single turbo setup on my 6Ltr,maybe something in the range of GT42/45 would be nice:).

Bigger boost with a bigger fuel setup will be nice. Also bigger dump pipe you can fit off the turbo the better. Assuming you're running the big exhaust housing aswell? 1.06?
The power is still nice and will have 340 in it with the boost wound on.

hi mate as i said figures on dyno will come !!! but if you drove it now ie at 304rwkw compared to 270 it will blow you you away the difference is huge ie torque/ power at lower revs etc etc!! plus the turbo rush!!!

yeah i guess thanks for the help ill keep you guys updated im picking the car up saturday so ill let you know how it goes hopfuly i can post a dyno sheet up cheers boys

Turbo is to small. Figure on 330rwkw at most. It will be a fast 330rwkw if it makes you feel any better.
BlueSS
18-06-2010, 11:12 PM
Ouch.. I wouldn't be to happy with that result... the turbo is a bit on the small side for a 6ltr but it should still work better than that..
Who's doing the tuning?

I would cry heavily if that sort of $$$ investment on FI netted me 304rwkws that is LOW cam territory...

Hey guys i picked the car up last night. it ended up makeing 320rwk with 930nm or torque on 7pis they reackon the tune is very concervative an theres more in it if i do a fuel system an more boost the car drives well an going from 270rwk with 600nm to that it is a differance but i still want more.. if i had enough posts i would put a dyno sheet up but i dont :( it dosnt idol well at all tho when i first got it it was ok but now it hunts really bad its gotta go back again but im happy so far for a street car it goes well i deff want more power tho!!!!!!!!!!!!

Hey mate. A walbro with 60's will support over 380rwkw safely. Give it 12psi and you will make more power but with the GT35 you are pushing shit up hill. Slot on a bigger turbo and you will be rewarded hugely :)

Hey guys just wondering if any of you guys have had problems with tunes. as yous know iv had the turbo fitted to my 6.0L vz. it got tuned last week an i have had problems ever since. i have a mate who is right into tunes an he has hp tuners an dose his own stuff. we put his scanner on to have a look and see what was going on an were shocked. the hole tune needs to re done again basicaly. It wont idol right for starters its like a pig all over the place an running rough as. Apparently the VE table is wrong, the spark table is wrong the injector settings are wrong, there running open closed fuel loop so when im cruzing an i ease in the throttel when it comes on boost its hesitates because once side of my engine is running rich an the other side is running lean.. its like there thrown a tune in witch was wrong to start off with an off set everything to suit the wrong tune witch is all wrong anyway... an yeah there is meany other things that arnt right im pritty anoyed seens it wasnt cheap for the tune..

Now thats the thing hey... One persons example of a Shit tune can be ones example of a good one :) Most tuners who look at someone elses tune would be quick to point out the negatives....... Anyways good luck sorting it all out

Before you go any further with opinions on suggestions in this thread, speak to the tuner. Discuss the problems and suggest they have another look at the tune (if they don't suggest it first). Don't blow what could be a simple mistake into something much more than that.

It was unexcusable even just how the car idled and how it could be delivered in that state. It was hunting from 500-1500rpm. And I know that on a phone call regarding he was brushed off because they were the was to busy... I'm with monta it's very very dissapointing.

Yeah it's shit man I hate my car at the moment I'm over all the bull shit.. There gunna have another go a fixing it if they carnt get it right this time I'm gunna try an get my money back or some of it because it's a joke they should of told me if they couldn't tune it an I wouldn't of gone there. I had alot of respect for this workshop that's why it's even more disappointing toils wouldn't expect it from them. I was about to spend alot more with them on a brake up grade, fuel system an clutch but I don't think I will bother now..... An yeah thanks I think I will go see them someone ells told me I should to after the problems I'm having..

This is true, some tunes are done in a different fashion to achieve the result. But some things are just wrong and should not be done.

mate... what shop is it? if you dont let your fellow ls1 comrads know and save them from this kinda hassle your just as bad as the tuner... report this tuner so the wider ls1 community can shame him and his work if he continues to be like this... theres already enough ppl like this in the world... we dont need them working on our cars...
We are a group of motor enthusiasts and we should ALL be looking out for each other.. like a big family.. thats just my opinion!
And for some advice for you.. i would be walking into this tunning shop with my car parked at the entrance of his garage... and letting him and all the customers know about this problem.. then i guarantee he will fix of refund your money... trust me ive done it lots... he will lose more business and income if you are persistent and he cant really stop you from sitting out the front of his shop and making customers aware of his dodgy dealings!
sorry about getting revved up but this kinda stuff Shits me.. you pay for a service.. you get a FRIGGEN service!!!

It's just as likely the car runs shit due to a poor turbo kit installation, which by the sound of it wasn't done by the tuner. Would you like to have a potentially good workshop/tuner tarnished when it probably isn't even their fault? Pointing fingers only gets you so far.
B-REX
28-09-2010, 05:51 PM
A few facts about this car.
The turbo installation is very neat and professionally done.
The idle was steady and driveability was good BEFORE it was tuned. (It was gently driven to the tuner with the original 1 Bar tune before tuning)
The car produces good power and drives well at WOT.
It has severe problems when idling, with the idle speed surging between 200 and 1200 rpm and stalls if you are travelling and put your foot on the clutch. And worse when the A/C is on.
The car has been taken back to the tuner and is no better !!!
The manager of the company in question was advised of the problems and said he would personally retune it himself but it looks like that never happened. The car still not fixed.

Mate why would you say the kit was poorly installed when you have no idear!!! It's all to do with the tune end of story. You havnt seen the install job its one of the best install jobs you will ever see a lot of time an care as been put into it by the person who installed it he did a amazing job!!

VZ 6Lt, was this a factory 6Lt or transplant?
If Factory, then the E38 ECM may be throwing up some new challenges for the tuner. They are a very different to to the older LS1 controller and have a habit of "learning" bad data when things get changed. A common example is the idle control initially behaving and then drifting out. If you want to check this, reset the ECM by....
warming the car up to normal temps.
turn off the ignition
Open the bonnet and engine bay fuse box and pull the "ECM" fuse. It's a red 10AMP job closest to the strut tower / drivers guard corner.
Turn ignition to "ON", do not turn to "start"
Wait for error chimes and error displays on the dash.
Turn ignition off.
Replace fuse and fuse box cover.
Turn ignition to "ON" and wait for OK check.
Press the accelerator to the floor 6 times ( actually I'm not sure if this sequence does anything in the E#*, but it did indicate the LS1 PCM should not redo its idle learn function )
Start car and test idle.
If it idles OK after that, then you know it's learned data upsetting the tune.
