I'm new to tuning and the LS world. I am helping a friend (brother-in-law) with his "dream build" over the past couple years as I've had time and when he could afford the parts. I Recently rebuilt a 4.8 mated with a NV-3500 in a 98 S10. The build on the engine is nothing special with a texas speed cam, Intake 0.370, exhaust 0.353. The heads have a trunnion kit with 660 springs, with beefier push rods. Hi-output oil pump. The rest of the internals are stock. 102mm throttle body. 42lb E-85 injectors. I'm using a PCM from a 2000 Chevy truck OS-9381344. I'd gladly accept any advice particularly with the PCM department. I have tuner pro, PCM Hammer, universal patch. Using a ODB Link MX+ for communication.
