No doubt!

My car had no valve train noise and I stepped 6 shims up to the next size cause they were beyond max spec! Thats crazy, how bad does it have to be if you are getting valve noise I wonder. That makes me think they put in the smallest shim possible to get within spec, so within 1k miles you could already be out of spec. Hints service 1 check, I bet they do not fix the issue though and they just replace with the same shim.

The car sounds and drives amazingly diffrent and I would not want to just flat out say it added 15hp but the butt says diffrently lol. It revs soo much smoother and faster, sounds crazy but if you see my posts about half step shims that could be another 10hp out of easy reach =-(

I would half step about 10 shims if that is any indication...!

I replaced them all reguardless to eliminate all wear from the valvetrain call me anal I guess...
