Bogging around 2,500 rpms

[OMGls1jz]

hey guys i just noticed this week that at part throttle my car bogs around 2,500 rpms but doesn't bog at all when at WOT. it doesn't throw a SES light either. if i give it part throttle gas from a stop, from 1,000 rpms to about 23-2400 rpms the car feels fine, pulls strong but as soon as it hits 2500 rpms and past it bogs alittle and feels like i lost some power. what do you guys think is going on? LMK



thanks, toua

what mods do you have

[OMGls1jz]

lid, aftermarket y-pipe bolted to the stock manifolds with cutouts on the y-pipe, and the y-pipe is connected to the stock exhaust. this also happened when i was still stock.

That happened to me as well. Check your MAF sensor I replaced mine when cleaning it didnt work and solved the problem. Good luck

okay thanks, i will give that a try. if it isn't the maf what else do you guys recommend doing?

[BMJ99Z28]

The seal that goes around the back of my lid got sucked into my MAF one time made it do all kinds of weird shit. I'v also heard of the oil off an air filter can do it. I'd try cleaning the MAF first since its so easy.

It may also be the MAP sensor

okay i changed maf's with my bro and it runs a hell of alot better. so i'm guessing its the maf.
