2011 cts-v
2011 cts-v We had a 2011 CTS-V come to us because the owner was unhappy with previous work done elsewhere. The owner had sent the car out of state to a self proclaimed CTS-V "specialist" for a cam upgrade, blower porting, pulley change, and of course retune. Long story short the car came back and on an independent dyno that the owner used the car made pretty much the same power as before it left and after some back and forth with the other shop the car ended up with us. Baseline was 524/474, we then installed cat delete pipes (car still has stock manifolds) and it picked up about 15/12. We then retuned it and cleaned up a lot of the part throttle tune, ltft's were between -15 and -20 then went to work on the WOT tuning. Final numbers were 580/504. Needless to say the customer was happy with the gains but for verification went to a local dynojet he knows and made 643/641. This is why we can't race dynos, lol but the owner is happy and finally feels the car is making the power it should.

it looks to be around around 175 hp and 270 ft lbs at 3000rpm is that right? The min max box is in the way. I like the story, and have seen it many many times. I hope business is up for you guys.
