Ok, so i have a 3" GM MAF, With a MAFT. Only mods are 2 1/2" turbo back exhaust, and B16g turbo, i dont wanna put anything else on till i figure this out. Im not that familiar with the MAFT yet, ive read through some of the tuning procedures, and im having some problems, My car will idle and run fine, but when i drive it, it will get up to about 3k and start bucking and running like poop, i have a Palm with MMCD for logging. and ive been trying to find out why its doing it, but the only strange thing is that right before it happens the o2 voltage drops to 0 for a second. But i will keep doing this for about 500 rpm and then when it gets closer to 4K the MAF Signal drops to 0hz and stays there and then my FT02 goes right to 100% and it runs great, untill i shift, then it starts all over again. and there is no knock, maybe 2-3 counts sometimes, while this is happening. ![Bang Head :banghead: :banghead:](/styles/default/xenforo/smilies/banghead.gif)
