I have the True Flow XDI intake and it keeps tripping the check engine light with a P0101 code (MAF sensor). I have uninstalled and re-installed the unit several times. Disconnected the battery and cleaned the MAF sensor with appropriate cleaner. Nothing has helped. It originally took about 200 miles for the light to come on. Everytime thereafter it has returned after only 25 miles or so. I have returned to the factory box and the light has not come back on in the last 300 miles. Has anyone had the same problem with the same or different CAI? If so, have you resolved the issue and how? I have not been able to contact True Flow. I may entertain a different unit. Any suggestions that won't mess with the computer? Any and all ideas will be entertained at this point!!!!
