[No Style 135is]

I'd like to update this thread. I have '13 135is, which comes with ppk2 and pe. Today I got Dinan S3 installed SW. I have a Wagner Tuning evo 1 com fmic along with ER oil cooler.

First impresstion, crackle, pop, snap are still there. I feel it sounds a lot deeper than ppk. The upshift is also deeper in WOT. The pop and crackle is also lounder in the first gear. Overall, I'm so happy with Dinan S3.

Also, the acceleration lag is gone.
