2009 Pontiac G8 GT, 6.0 L L76 engine
lifter died so in for a penny, in for a lb. Decided to do a full DOD delete and some other work since the car has 149K on the clock.
DOD delete kit, new LS3 rockers (because of the noise), new GMPP LS3 Hot Cam, New LS7 lifters. new oil pump and assorted other bits.
Car started on stock tune - surprised us as it ran and kept running for a while. got hotter started to stumble - idle irratic always. Reved - but it would die if you dropped off the throttle quick. Yes we knew it would need tuning this was mostly to get the oil going and check the rockers and pushrods out.
I asked in other G8 forums if I someone could send me links to a stock Pontiac G8 GXP Automatic tune. So I could base line to the LS3 auto car.
I got 2 that I'm working with but any help would be appreciated. Also with the GMPP hot cam I'm now at or near the LS376/480 crate engine so if anyone has a tune or a line for those I'd also greatly appreciate it.
I am wanting to go for driveability not power since I DD this car. Thank you again.
