Tuning Help Please!

Ok, so I'm looking at getting my LS1 tuned. I have passetter LT's w/ ORY, ported TB, Descreened MAF, Whisper Lid, Hooker cat back, NGK TR55's, 3.73's and thinking about a Yank 3600 before the tune. BTW is an auto. Now I just talked to a tuner and he said with those mod's I would only net 300hp after the tune to the RW. His price was $400. Is this right???

No should be in the 330 range at least.

Thats what I thought, and I've talked with another tuner and thats what he told me to expect. I mean if our cars came stock with, lets say 295hp, and there are plenty that were way more than that, then this guy's telling me all those mods were worthless?

well if he is considering the stall and it being an auto, it will dyno lower than say same mods on a 6 speed...dynos should only be used as a tuning tool, unless you want to brag on the net about it. track times are what counts..

Use a dyno as a tool, not the end all.

Certainly. And remember, an auto has more parasitic loss through the drivetrain than a manual. Plus, a dyno is only a tool. The track is the true measurement of performance.
