    Good choice, .....I did lid and Maf(Gmaf with cold air tuning) as my first mods. It was ok till I did my LT's and True duals. Then I kept getting the lean code. Put my stock maf back in and no more codes.

    I'm not really 4 or against an aftermarket MAF, but here's a short story...
    When I bought my car (used) It had stock Z28 airbox w/K&N drop in filter. After I got the car home I realized it had a Granatelli MAF so I drove the car around as is for a couple months or so and had no problems. So I decided to put on the FIPK that the previous owner put in the trunk when I bought it.
    Soon afterward the car started throwing codes...(bank01lean, bank02lean, maf out of range) One or two or all would pop up every so often (once a month maybe) So I don't know, maybe I should try a stock MAF...

    My car occasionally misfired with the GMAF. Got real bad when it would rain to the point of being almost undrivable.

    The Granatelli Maf tuned for cold air was causing mine to run rich but it seem like it did have a little more power around the 3500rpm and up but could not tell for sure with out a dyno. If you still want one have a brand new one that was on for a day. $150.00 for it.

    Just for what it's worth

    I already had SLP long tubes, 3:70 gears and the Predator tuner. After the header and Predator installation I had a "check engine" light show up so I took it to a Chevy dealer for a diagnosis and they said it was running lean. It never missed or ran bad and I was doing high twelve seconds in quarter at 111 mph. I installed a Granatelli MAF, no other changes unless it was pump gas or atmospheric conditions, did my best time of 12:47 and 113. I used the Predator to enrichen the mixture and the check engine light went away. Although I'm still solidly 12:6 12:7 I've yet to break 12:6 again, even after going back to what I thought was the lean setting. Nor has the check engine light come back on. I even tried a throttle help as far as I can tell. Go figure! Make of of this what you will but it's the truth as I know it. Sam
