For all of you who have the Mrev, 5/16 spacer combo. I have the copper Iso thermal kit btw. I was wondering if you all are getting a slight but audible high pitched hiss whenever you press the gas. Is this normal? Doesn't seem to do this in hot weather.

So yeah, I got my Mrev 2 and 5/16 spacer installed yesterday. It's been hot in MD for the past few days 90 plus-ish. I could feel slight gains, which was great, but honestly was feeling a lil bit underwhelmed.

Well, that all changed, quick. I just went out tonight (10PM) to make a quick 7 eleven run. OMG my car has finally awakened. I mean I knew that heat and humidity was robbing me of power.. but wow. Mrev 2 plus 70 deg weather = heaven. Now the car pulls like I've always thought it should've from the factory. Great stuff.

 

do you have an intake?

 

how is the car running at idle seems like there might be a vac leak some where
