I did the advise from a previous post and got the numbers for the MAF of a stock GT500 and added 20% to try to get close to the 123. I also can't say was ok and just adding the cold air. The engine was torn down and redone with tons of changes and bolts on for the build. At one point there was thought maybe the MAF has went bad. But when you look at the log it does the MAF data moving around not like froze or stuck. So thought it was good. But could a bad MAF sensor cause something like this?
