will be doing a dyno run later as we finished the car kinda late but did a stock run and the it made 334whp

butt dyno says it feels way faster now after the dp and tune

sounds insane ... highly recommended mod for any B58 engine out there

will be talking sound clips later
Thatís fantastic news! Looks pretty darn good for a fitment. Thatís a mighty clean garage bay. Reminds me of the auto hobby shop on Vogelweh in Germany. They make everyone mop their bay after use and wipe down all their tools before the next person can come in and use it.

Canít wait for the sound clips and the dyno results! Iíve been itching to mod the car but other priorities at the moment.
