Default TTi x package 583/549

Got a call wednesday to tune a basically bone stock corvette with a TTi twin turbo package. Didn't know much about the build since another guy did the install. Car ended up putting down 583/549 without really any timing in the motor and the fuel set @ 11.75-11.90. How do these numbers look?

What does the overall dyno chart look like?
Boost level?

I'll find more about the build today, TTi said the car should make 6-8psi. I have a feeling that the car had bad gas or 91 octane. Power peaks around 6000.

Sounds about right for the setup on a stock bottom end. The torque might be a hair low, but could be the dyno, etc, etc... nothing I would worry about.

If that's a Z06, then the numbers are abotu 100 RWHP/TQ than they should be. If that's a regular C6, then as BLOWNZ06 said, that's about right for a stock-motored car.

I'd like to add that you can add meth to the car, tune in another deg or two of timing, and add maybe 2 more lbs of boost and you'll probably pickup about 100 more at the wheels (safely!)!!

Shoot me a PM if you need any help with the methanol side of things. I might be able to help you.
