So my motor was tuned and has cats, but the exhaust is still extremely potent. I always leave a blue cloud when I go WOT and with normal driving I get about 9 miles per gallon. I understand the large tires and poor aerodynamics don't exactly help, but other that have done this swap seem to fare much better in terms of fuel economy. Does the MTI X1 really let that much unburnt fuel through? The motor runs great, but I am starting to think it is getting too much fuel. Thoughts?

Mine puffs out a cloud too at WOT, I found it to be the O2's out, have you scanned them?

Unfortunately, California has made it illegal for places like autozone to give out their readers. I need to go to a mechanic or buy my own.

Yea, I hear ya. I have a friend that runs a Tranny Shop, he has a scanner and we hooked mine up and found my problem.

I figured out that my speed density calibration was off. The motor thought it was getting way more air than it was, and used tons of fuel. I plugged my MAF back in and it got a whole lot better.
