2003 Vette twin turbo done with OS3

Thanks guys, this makes tuning them in a breeze. We upped the boost to 10-11psi later and made 640rwhp. Totally stock engine otherwise and still has its factory cats.

Nice one, 640Hp at the treads sounds like a whole bunch of fun to me.

Add a few bolt-ons and you could be above 700HP. I think I would want to modify the lower end before running 640HP all the time.

I would love to have twin turbos on my baby..

Well, what I do with these turbo cars is set the boost at 3psi and work my tune in, then get 5psi, 7ps, and 10psi and kinda interpolate between all of them.

That way the tune is good for whatever he gets greedy for. 11psi was definately the limit on the fuel system.

I would say the car should be driven on 5psi as that is what the dyno graph is forand where the waste gates open. IT makes stuiped power at 5psi anyway.

I talked to them today about how the car was driving.. He said.. damn good.. however I put it in a ditch!

The car is flat out dangerous.. even on 5.5psi.. it just gets way to squirly in a vette with that much power.


He didn't damage it too much.. just clean the mud off it and its good to go.

Any tickets yet??

Nice! That much hp in a vehicle that is half the weight of mine sounds like fun.
