well i have an 05 6mt coupe with test pipes, cat-back, mrev2, 5/16 spacer, z-tube, and pop charger. Which would be a better investment for me i dont foresee FI anytime soon and im looking to beabel to drive it normally but i alos want the extra power when i need it

 

Hi, I have an 06 AT coupe. I have a 5/16 spacer, full cat back Stillen, injen cold air intake, high flo cat, unorthodox crank pulley. I'm very new to this, what is a n MREV2? I want to get as fast as possible without forced induction.

 

UpRev's Osiris is a great way to go with an NA car. The UTEC is still somewhat acceptable for FI cars, but is generally not used for NA cars an longer.

MREV2 is a modified 287hp lower plenum designed to give more lower and mid range power to revup engines. You have an AT so you don't have a revup, so it wouldn'y be a big improvement for you.

 

You can't really compare the UTEC to the Osiris... one's a piggy back, the other is a reflash. In other words, one is still tricking your ECU while the other is a reprogrammed ECU...

 

What would you suggest I add to make it faster?

 

If you're looking to tune your car, I would suggest Osiris over UTEC.

 

Yea, either get Osiris or a standalone, but don't fool with a UTEC on an NA car.

 

i might just forget all of this and just go s/c or turbo. do i need a new hood with a s/c?

 

Only the Stillen. You can use Osiris even if you're boosted... it's got a lot of really great features including multiple maps that are selectable by using your cruise control buttons, and it doesn't interfere with your cruise control functions.

 

What are the issues with the early 2003's as far as using the Osiris?
