Did a cam swap and looking for some tuning help - I'll post a pass and my boogered tune, and have a feeling I'm WAY off with the tune because factory cam and tune was quicker in the 1/8.
Here's the lowdown:
Truck is an 85 gmc 1500 with an lq9, headers, comp springs and a howard's cam https://www.summitracing.com/parts/crn-1449041 ~2200 stall (factory 2000's ss camaro) 3.73 gears and trans-go hd2 shift kit.
Did some SD tuning to dial in main VE, and pasted that into the factory tune and reverted to MAF. I haven't tuned in the MAF yet, but the cam seemed to not really need that much? Again, total newbie here.
Here's the 1/8 times:
Factory cam and tune did a best of 9.128 @ 80.02
New cam and booger tune did a best of 9.237 @ 78.98
Obviously i did something wrong, or this cam is garbage? I have a feeling it's my tune. I'd be less shocked if the slower time came after the shift kit (which is definitely shifting quicker).
I'm pretty sure that histogram is of the same tune, but the only thing that would have changed is <1* of timing and some shift points. I realize the KR during the burnout and probably should address that too?
Thanks in advance
