Not my car and I haven't driven it. Would you be happy with this?

Seat of the pants dyno tells me I got significantly more torque on my VE with extractors/catback/air intake/tune.

I'm surprised to see less torque than stock with this setup through the important part of the rev range. Surely any fool can make more power at high rpm with more air flow?

Is this typical?

I'm only seeing Power (KW) and AFR on that dyno graph, no torque in sight.

Agreed, you're reading the graph wrong, it doesn't have torque on it.

Despite the glorious photoshop attempt, I know the workshop where this thing was tuned. Tough dyno that always gives a lower figure.

Top sheet is from APS in Frankston, bottom is from the shop in question. Same car less than two months later. Mods as per my signature.

Just saying the old line of dynos are a tuning tool. The car didn't magically loose 30rwkw as I drove up the Hume.

Good stuff, thanks for setting me straight. The text on your image is much easier to read.

I thought I may have been missing something and did not want to make any negative comments regarding the shop in question.

Is that a bit disappointing for an LS3?
Also is Canberra at altitude so some KW could be lost?

Have looked at Walky packs & are overpriced for their outcomes. They bang on about maintaining your factory warranty blah blah but a read of the fine print you'd have buckleys of a claim! Best see a very reputable Tuner ideally someone who has been working with LS since inception & all will be good :deal:

Like I said, it's a tuning tool. On the same day as my 263rwkw, a manual LS3 GTS with similar mods ran mid-270s.

Peak hp is of little interest to me as dynos vary. The question is, what is the difference/improvement compared to stock?

I understand the before and after numbers can be tickled, but assuming it is done honestly, I am interested to see the distribution of power and was wondering if the Walkinshaw juggeraut had been infiltrated with emissions.

Happy to see I have the bull by the horns as it did not look believable, hence my asking the question.

I am in the market for a new vehicle and a little shocked by the cost of packages these days. $6K is good chunk towards an LSA HSV with a lot more options.

Anyone have tips regarding better value packages?

That's interesting Mick as the last two dynos APS have had are pretty tough compared to most others in the area. Can't speak for the readings way back then.

The most important thing is how it feels and drives now compared to before. Obviously value for money is harder to judge......

That said, IMHO Walky stuff is overpriced - just pay for the name....... ��

To my knowledge, Walkinshaw have no claims to meeting emissions standards. Their packages can still cop you a defect notice.

But even though they're essentially the same package, things can vary greatly across the country depending on the workshop installing/tuning it.

I thought the tune was not even custom to each vehicle

I reckon the interpretation of "custom tune" can be pretty broad...know of a lot of shops that will charge an arm and a leg for a custom tune when 99% of it is generic, it's just strapped to the rollers for half an hour and a couple of parameters are tweaked. They don't even get road tested

I agree Gary,
Luis at APS is not the guy to see for a happy dyno sheet
but IMHO he would have to be one of the absolute best tuners in Australia & gives amazing customer service.

Dyno measures torque vs wheel speed to calculate Kw

APS dyno sheet was 4th gear (closest to 1:1 ratio) Gentech was done in 3rd ( NFI as to why) - good old Mainline vs DD debate

Did you guys see that ?? Nothing like comparing apples with apples Mick, guarantee your magical non- missing 30kw was somewhere in Canberra !

p.s hope you've been well mate !

Change in air density will make some difference though. My cammed VF was tuned in Brisbane on a 35 degree day, when I brought it back to Toowoomba it struggled to idle a bit on 4 degree mornings until it compensated itself. It's fine now but initially was a huge pig while it learned the change in air density (being 600m up in the air and 30 degrees cooler).

How good the tuner is will make a huge difference to everything also.

I honestly think LuisS explained totally why the dyno results were so far apart in numbers when he pointed out they were done in different gears.:goodjob:

I did note the 3rd gear but also thought running in a lower gear inflates the figure? Unless it was run in 4th and the dyno was set at 3rd...I'm not sure how that effects the readings. I'm surprised you can change the gear selection in Shootout mode too actually

What's with that AFR? Mid 11s at full noise seems pretty soft to me for a bolt on car.
