He did a few changes as far is timing. But this sudden drop of power occurred before pulley swap and it was just after a new exhaust. I don't think the ark is a bad exhaust but I'm think something is just not sitting right in the tune/ecu. Not to mention that coop has one on his TT g37.

We went from 460 whp peak to 340 And then it shows to start building up power again
