Jordan 679

First post on the forums here with my recently purchased 2009 C6 4LT Coupe. The car has just over 55k miles and is the second corvette I have owned, the first being a 1990 C4. I decided to have a baseline dyno and tune after I installed the Airaid intake today. Big thanks to RPM Motorsports of NC for helping me out with the tune.

Baseline Hp: 375
Baseline Torque: 379

It was running very rich so we had a lot to gain with A/F ratio.

Tuned Hp: 410
Tuned Torque: 403

Car is bone stock other than the intake.

Nice!

Welcome to the forum!

Nice! I have a club dyno day next week & a tune scheduled shorty thereafter.
This gives me an idea of what my 13 will put down for #'s.
My 1st dyno wil be bone stock, including the intake.

Automatic or Manual transmission? With the baseline numbers, I'm assuming auto.

Its a manual. Seemed about typical for what I have seen. I thought the auto cars dyno quite a bit lower than this for baseline...?

35hp from a tune? do you think that air raid had much to do with this or would a re-tune of a stock be close to that?

Jordan 679

The baseline is actually not a true baseline as it was done with the intake installed. I gained the full 35 from just the tune. Wish I had done the baseline without the intake but didn't have the time. I was the last car of the day.

I would assume my numbers would not be nearly as good without the intake installed but I really have no proof.

Outstanding gains

Seems like pretty good gains throughout your curve.

Were your baseline/final values "corrected" at all? How much did you pay for your basic tune?

Jordan 679

I don't think either were corrected but if so, they both were. The tune was $350 but all future mod tunes are free with $75 dyno fee. That was the kicker for me since it will get headers and cam in the future.
