2010 Chevrolet Corvette - Consumer Guide Automotive

Reports 430 (436) HP for 2010 base model Corvette.

I'm sure you can find differing reports on the WHP on the base model but one place I read put it around 380.

And, considering your posts, you don't need me to tell you the dyno makes a difference (showing a dyno itself doesn't mean much unless you know which dyno it was and had a comparison chart to place it againt other dynos). I wouldn't pretend you hadn't thought of that.

Anyway, good post, man ! +1
I think the 430 is crank hp and the 380 is probably wheel HP. The base vette is 430 crank HP, as is the GS vette. The Z06 is over 500 and the SC ZR1 is over 600. So a base vette fast is still kinda nice. But with an aftermarket SC it would be nice to have the power lower in the rpms and as I like the low end feel of power, like from a stop or when stepping on it while crusing at a moderate speed.

well, this new tune definately improved alot on the low end! i went through alot of different tune and this tune has the most power. but of course it's not a vette or turbo charged. you will never get that low end as powerful as those. it's much funner to drive now that's all i can say.

So i got a tune today by SG Motorsport | Welcome. Everything is running perfect now. No more pings, the throttle response is night and day, and the boost feels much better. The baseline run was at 375 whp and after the tune it's at 395whp with 298 lbs/torque. This was done on a dynapack 3000 dyno. Will have the graph up as soon as i get it scanned. The most significant gain was during 3000-3400 rpm where it gained about 20lbs/torque from the tune which i felt immediately.

Im sure it is more fun. So the throttle response from a stock Z to the SC Z is a big jump? And Im sure the power jump with it is noticeable too?

Can't agree with you more!

When I started reading about this SC--initially rated at something like +155 WHP--I wondered about the internals. Just as I wonder about the internals of ANY engine having its WHP increased by 50%. I mean, something's gotta give.

I agree with the comment regarding Stillen posting a more "honest" remark about gains and having people actually get a few more HP than using what appears to be a tune that's going to be damaging in the short run to the engine just for the sake of posting a big number.

Got the new tune and making less power with this tune then the last three tunes. Throwing in the towel given stillen enough time i give up! Never buying anything else from stillen and i would recondmend no one buy this kit its no where close to what stillen advertised.

What power are you now making?

Nitex 09-08-2010 12:59 PM
At this point i cant blame you. IMO get a partial refund (screw the CARB) and find a local tuner that can tune their product better than they can. :shakes head:

376 on a dynojet down from 396. baseline with high flow cats and exhaust 302. thats a whopping gain of 74. far cry from the 155 stillen was advertising. will post dyno sheets later going to pick up car now drivabillity is better so im told.

Wow, what a dissappointment.

Slynky 09-08-2010 01:22 PM
What does this thing cost, installed...anyway...?

Chris@FsP 09-08-2010 01:26 PM
Those numbers are def a little low. When we ran their newest tune on a DJ, we came up with 389whp/290wtq, which is almost identical to our custom tune on a different car (although the ambient conditions on our custom tune were much worse than when we dyno'd the Stillen tune).

I know this is dumb! Ever thought about removing your HFCs and try using the stock cats?

shumby 09-08-2010 03:23 PM
^^^ not dumb at all. You will see a small increase in HP and huge increas in TQ. I am still surprised that stillen has such low TQ number compaired to the other SC kit out there. with a 6 psi pully it makes 350tq
