[QUOTE="Stewart_H, post: 8066552, member: 20384"] You do not need a tune to run the 90mm, as long as the 90mm is an OEM unit from Ford for the '01+ Lightning. Zach, when I purchased a 90mm for my '99, I went to the dealership to have my PCM flashed with '01+ Lightning specs so it would read the 90mm properly. The dealership told me the adaptive learning and the fuel tables would easily compensate for the upgraded MAF. Because of everything I'd read on the forums (almost eveyone said a tune was needed, only a couple said it wasn't), I kept insisting a reflash of my PCM was needed. But they literally refused to take my money. Who woulda thunk, eh? For once, the dealership knew what they were talking about because after installing the 90mm, I never threw a DTC nor did my SES light activate. Stewart [/QUOTE]
