I was thinking of getting a tuner for my truck here soon. I looked at URD and seen this URD MAF Sensor Calibrator. I think this would be a better choice of the problemed unichip. I would like to adjust the fuel trims for power and maybe also save some GAS. The machanic would put on my headers said that the truck runs rich, it showed on the dyno sheet. Anyone uses one of these calibrators? Or should I just wait for a chip besides Unichip? I got a K&N intake, Banks single 3" exhaust and DT Longtubes.
