Default dyno ?

After my mods on the dyno my #'s were.. 1st run.. 290.6RWTQ, 251 rwhp 2nd pull 287.7 rwtq, 253 rwhp..what would i be putting at the crank? I know have 3:73 gears would that change ne thing on the dyno run? I used the sct 3 programmer to calibrate gears and change to 93 octane and rev limiter to 6200..If i was to get a dyno tune would that make my #'s go up thanks guys!

What are your mods? I got 299 flywheel horsepower considering an 18% drivetrain loss. And 342 torque at the flywheel with the same loss. This must have been on a dyno jet. A dyno tune will help out a little but to be honest if you already have a custom tune it will not make a HUGE differance. I believe gears have a little impact on dyno numbers but I'm not too sure what the deal with that is. Nice numbers though.

A custom tune and a dyno tune are the same thing. Gears will generally lower your top end HP a little but give a lot of low end torque.

Bad04OrngGT, what is sct 3 programmed?

CAI, thats all I'm doing to it. I'm trading for a cobra in 2 years or so. So to keep the value high I'll keep it pretty much stock. But the cobra will be heavily modded. Was the dyno on a dynojet? Those are pretty good numbers.

What's the deal with your TQ?

Your HP numbers are extremely high for a bolt-on GT that doesn't even have headers.
