First timer here and I am not a GM guy or a ECU tuning guy either but I rebuilt my brothers G8 last month and I'm trying to give this car a new life, I have got the tuner working and got the car idling.., but it is not running well and I need help, winter is coming fast up here Michigan but I would love to hear this thing at least idle and drive around the block better than it is now.
Here's what was done and most likely a terrible tune to view:
BTR Stage 2 V2 cam
Texas Speed dual valve springs
New Trunion kit
LS7 lifters
Chromoly stock length pushrods
New High Flow Melling oil pump
.010 cut off the heads
ARP studs and bolts throughout
1 3/4 longtubes
Ebay special exhaust 2.5 inch through
Stock Converter currently and the push through is very noticeable but not over whelming.
