i might be wrong but I think my car has Cobb stage 1. I bought it used and it Pumped 195.72 whp and 203.66 tq. Which is very close to Cobb's stage one 195.4 whp and 203.1 tq. is there anyway I could find this out?
that sounds about right. iam running stage 2 now. stage one does feel smoother , see if you can get the previous owners information and contact him
I have only driven one other one and it has no exhauset and no backseats and I would have to say my feels smoother than that.
