I sent my car to a local shop for a few mods, cam, long tubes, true duals, gears, etc. My car is a 2000 ss with a six speed, with right at 80K easy 2 owner miles, the reason I say easy is because I know the previous owner, and she drove the car daily and very mildly. I talked to the shop and they got a baseline on the dyno of 296hp stock. The problem is now theyre are only getting 338hp and they say the car is running beautifully but only making 338??? The cam they used is a TR reverse split on a 111, Pacesetter LTs, a custom lid, TSP 3" true duals, 4.10s. They are telling me the car should be making 400+hp, and from everything I have read I think it should too. The last conversation we had there was talk of possible cylinder leak by? The car was very tight and never modded when we started. If anyone has any ideas I would love to hear them. Thanks

Yikes! Any codes and has the shop tuned LSx cars on a regular basis? Dumb question, but do you still have cats on the car?

i wonder why they chose a reverse split cam....
4.10 gears will absorb some of the rwhp numbers. i went from 3.23 to 4.10 gears and lost 24 rwhp on a stock motor.
