ive been having trouble with a code33 after much investigation i found that the granatelli adjustable maf sensor i purchased is not tuned for cold air induction and if u have cold air induction with this maf it will throw a code 33 which it is ,but on granatellis website they say if u got cold air induction to purchase a maf that is tuned for cold air which would b characterized by a C at the end of the part # my part# is GRN-350100 and there is no GRN-350100c but they said that tuning for cold air could be done on existing granatelli maf sensors,but i have to call to get details,sorry bout the run on but im just tryin to figure out what to do , wonderin if i can tune it myself(since its adjustable) or if im gonna have to send it in and spend more money to get it tuned for cold air?what does everybody do with there mafs when runnin cold air setup? any help would b great ,thanks in advance,Joe

 

Just call them. For the amount of money those things are they should fly someone down to install for you lol.
