Can any of you guys tell me how much total timing an LT1 has stock, and how much Madz28 chips usually add with their "power tune" I am going to put the hose on my car and need to figure out how much timing to pull out.

Thanks,
Rob

 

I just looked at my stock tune, total timing at 95KPA is 35 and at 100 KPA is 33. it appears that my latest tunes total timing at 100 KPA is 35.
