I sold the Jeep to help with the wife's medical bills. My non-smoking 34 y/o wife had a double-lung transplant last May, so the bills were getting out of hand.

As for the NW CAI, I bought it prior to purchasing the XFire.

Having a bit of experience with forced induction, there is no way in the world I'd increase the boost without a tune, or at least a minimum of a wideband to monitor A/F. With my Jeep I could adjust fuel and spark with a handheld controller to compensate, but I don't beleive the XFire has this option.

Eurocharged is currently running a sale on a choice of 181 or 185 with tune for 1k, so that's what I ordered. I also ordered the Johnson pump, since mine isn't working. I plan on ordering the $150 SiliconeIntakes heat extractor in the next week or so, if I can find the 14" I saw in the writeup.

I'm new to the XFire, so what's the best way to determine if the pulleys are stock and if it's completely mod-free, as advertised? Who knows, I may already have a larger crank pulley.
