Was wondering who all is running the URD MAF Calibration unit... Do you feel a difference, any dyno results, or accurate gauge readings of air fuel ratio before and after? I have a K&N air charger, Port and Polish of the throttle body, and a new exhaust system from the cats down... The truck runs great, but I wonder if the URD product will put that finishing touch on my trucks respiratory system that will truly make it PURRR.
Also, anybody know if TW members get a discount or coupon with URD??
