i want to oder the mrev isothermal copper, but i want to know if there is a huge difference with the 'plus upgrade' or not? i just want to get your guys opinion. i've herad that it'll add about 2hp from a friend of mine.

 

nawar, you dont need the copper, so cal isnt cold enough for it. as far as the plus upgrade, i dont know but i know you dont need the copper.

mrev is mrev

 

I doubt it does that much... I think it made a gain of like 1-2hp... but if you think about the price of mods around and how much power they make, $110 is fair for 1-2hp... even though the MREV itself makes alot more...

 

I figured WTF . . . For the price of dinner and a movie for the wife and I, why not?

 

thanks guys..i appreciate your comments

 

Might as well do it. I did, but my brother also port matched the lower intake plenum of the mrev to the actual intake manifold ports. Seems like a worth while mod, I am running 275 BFG KDWs and can break them free now, before I had a hard time spinning them.
