My mods are tbe, greddy e-01, K&N filter and a fuel pump. I plan on running about 21-22 psi... how much of a difference am I going to feel with a tune?

I've never gotten a ride in any other evo but mine so I don't know how well evo's tune. I've seen some tuned evo's running in the scca and a few more clubs but never been in one.

A freind of mine has a cobalt that was like night and day after his tune. His only mod was injectors.

My Porsche was a monster... I plan on trying to make my evo as fast as that but unfortunatly I'm going to need biggg turbo for that haha.

 

Biggest power mods for the VIII's are cams. A 3" TBE and tune yield about the same amount of power. Get some cams and a tune for a BIG difference.
