Well I had 4 MAFS before they got the right calibration and I had to send Russell flow sheet in to get them to get it right. Hopefully they learned something off my car and can get them right. Because there is only a few foci's with the 30 # injectors. You don't need to upgrade anything but if you want to go ahead. Good luck on your MAF and if they don't get it right the first time send me a PM and maybe I can help you.
