    Just wondering if a lot of you guys remove the MAF screen. Since i have a turbo i got to thinking that maybe it is a restriction to the BOOSTED air going through it. So if someone has done it and noticed a difference and didn't get a MIL, then let me know. Thanks!

    Exactly what kind of problems have you guys run into by removing it? All I ever hear is don&#39;t do it but no real explanation of why, except it will mess with your tune. Mine is removed and I&#39;m having minor issues at startup but I&#39;m not sure if this is the cause.

    It will lean out your tune tremendously.

    OK that&#39;s probably my problem then. When I had the truck dynoed my A/F ratio was about 14.2:1, I wouldn&#39;t really call that severe though would you, but enough to lose hp. Also at cold startup it runs funny kinda like it has a vacuum leak. I&#39;m assuming the computer is searching for the correct ratio until the O2&#39;s get heated up. Does this sound like a descreened maf problem to yall?
