just woundering if my cammed ls3 will fire with stock ls1 mafless tune just need to fire it up to make sure there are no leaks and everything is all good before taking it to get tuned

SO just to clarify...
You have an LS3 and running an LS1 PCM, Cable Throttle, reluctor etc?

I would get the Spark table and a VE table from a stock LS3...
Drop them into excel and then extrapolate the data so that it matches the lower resolutions and different scales that the LS1 ECM has.

Also do you have the correct injector flow rates?
If you dont have these right in the tune.... well VE tables wont help much.

I would also ensure that you have short term fuel trims enabled.

GOOD LUCK!
