CMCV = Charge-Motion-Circulating/Control-Valve


It restrics your engine for the soul purpose of increasing low end horsepower by 10hp but reduces high end horsepower by 10 and across a wider power band, it's there to increase mpg. So you gain 10hp from 1500 rpm to 2500 but lose 10hp from 2500 rpm to 5500. Your best bet is underdrive pullies an X-pipe and a Light Weight DS and an intake and tune. Together with the CMVC that's 365hp as a DS produces the equivilent gains to 25-30hp even though you won't be able to feel it.


"365 hp" isn't bad.

yeah i heard the pullies make your accessories run slower, sometimes even not producing enough power for them! i have an avic d3, so do you guys think the underdrive pulleys will affect that? or will it be fine?

thanks so much you guys!

Your underdrive pulleys can power your avic d3 no problem!

alright awesome! i think ill go with those and a driveshaft sometime this summer...I dont really wanna get an x pipe because i wanna still pass smog.

I am not a fan of an x-pipe with this exhaust setup......loses some of the deep rumble and adds a bit of harsness if you asked me! JMO though
