It's been previously stated that it's guaranteed to give at least 15RWHP out of a stock non rev-up motor. You can order them from Riverside's eBay store and if you have a Microsoft live thing, you could get a possible 20% off your purchase. Making the Iso-Thermal Spacer close to $200, which is quite worth it IMO.

 

where are u located? i know someone who can port and polish your throttle body, runners, and lower plenum. got a good gain, notice tq pull. awesome i love it

 

i am right outside of houston!

and no one ever answered my question about the Turbo XS UTEC?!?!?!

anyone have it??? heard some good things about it

 

If you're looking to get tuned, I'd suggest Revup's Osiris ecu reflash over any piggyback. Look them up, they're in Texas...

 

The spacer gives 15 rwhp?

 

on a REV up motor a spacer combined with a MREV2 is supposed to deliever these numbers. However ive never seen real proof of this. 15 rwhp is a lot to claim. Im sure it gives you a good amount of power im just not sure to how much exactly.
