Ok Guys I Have A Question? I Have An 04 Coupe. And I Put The Mrev2 In My Car. And I Noticed A Little Difference In Power And Sound. But Anyways I Now Want To Put The 5/16 Spacer On. Will I Loose Power And Sound If I Do This? Or Should I Take Of The Mrev2? Can I Have Both On There? Thanks

 

anyone?

 

I have both and felt that each added small gains in different areas of hp/torque curve. Thing is you'll probably not get maximum benefit without some type of improved tune. Some are concerned could cause lean condition if you also have exhaust mods so I'm waitng on HFC's before adding either the Cobb or UpRev ECU mod.

 

If your engine is running healthy it will do about 4-6 more HP.
