Bump...come on, no one has an '04 WRX that needs an AP? This is one of the best things you can get for your car! Everyday driving will be greatly enhanced.
Sold to member: gaitedgirl. Enjoy the unleashed power for your WRX! Gaitedgirl, if you you didn't know this already, with the AP you'll get better gas mileage too. How is this possible? Stock Subaru Maps are designed to run extremely rich, I monitored it with my wideband O2 sensor, you'll see the AFR's drop into the 8's! That's wasted fuel going out the tail pipe. http://mnsubaru.com/forums/showthread.php?t=11448 Again, enjoy and thanks! Forum Mods, please delete this ad.
