o-cha,
I guess we may not count hp then the way tuners suggest.
Going back to the point,
Why a four cylinders 2.0L with a compression ratio 10:03:01 have the same gain as a 3.0L straight six twin turbo with a compression ratio 11.3.1 ?
I also kept my warranty with the APR software, the same way Dinan is suggesting.
