need some advice. new to tuning bought hp and found it to be really intimidating. so to save time for my project i took it to a tuner and got some dissappointing numbers. so here is what i have.
stock bottom end ls1 with 317 heads. 228r cam kit from texas speed. 2.6 kenne bell with 60's for fuel. it is a return style setup with all aeromotive stuff. 4l60 blah blah blah. ive got the correct 2 bar map. Now heres the problem the car only put down 328 whp. is this correct? iats were in the 140's which seems to be normal for these heat pumps. timing is at 17.5. when i got the car back i realized that since he tuned with efi live i cant even access my pcm file. the car runs rough and surges. have i just wasted a ton of money and need to start over?
