I have a 2010 cobalt ss with FMIC, IC piping, CAI, catless DP+muffler delete, trifecta tuned 24psi. I bought the car with all these mods on it this past summer and i was wondering if the trifecta tune changed where redline is? Like where optimal power & torque ends. Please let me know! Thanks

 

Vince most likely left it stock(for good reason) because the stock turbo runs out of juice at 5000-5500 rpm. Raising the rev limit on a stock turbo tc in any other gear than first is very pointless.

I say first because fwd cars have issues with traction and a little rev limit raise in first gives you better traction going into second.

 

Vince leaves it stock unless u request different. Gms1 puts it from 6200 to 6500 that's where I asked Vince to put it. .
