FYI everyone if you have a part throttle bog in all gears as I had this might be a simple fix. Since buying my 2000 Z28 m6 I have had a contant bog at 2500 rpm in every gear. We checked hte a/f ratio at Jakes in June when the club had a pull day and it was super lean. I cleaned the maf thinking it was dirty tried all kinds of fixes, new fuel filter etc only to find it was a bellows leak between the maf and throttle body. Replaced the bellows made sure it was clamped good and it's fantastic she runs thru the gears smooth with no bogging. Hope this helps someone else, getting ready to dyno tune next week.

I replaced it with a smooth 3" rubber plumbing hose from Lowes cost less than $8 but got it tuned a week later. Phil over at Jakes put it on the dyno to clean up the other changes I made. After these changes, no egr, cats removed, SLP y-pipe, SLP lid with K&N filter, Maganaflo cat back exhaust, new GM performance wires and Denso Iridium plugs we got 320hp/334tq at the wheels with NO Headers runs great now picked up 3 mpg around town.Comment
