If you want a tune that you don't have to ever get looked at again that is pretty much near perfect in any way then pay Yavus the $1200 and get it tuned. He does not have time for time wasters who complain about price.
The guy is a engineer who happens to be a car guy, he could be doing a million other things making a monsta of cash without even having to touch a car but his service comes with a price tag and I think its worth it.
If you don't think its worth it then don't waste his time.
