Thread: Help boost problems

well im about at wits end whit this car......I have fixed vacuum leak after charge pipe leak after exhaust leak....car still will not build more than 1-2 psi of boost. I thought I had fixed the problem the other night as that was the first night I have seen positive pressure in the boost gauge but nope the boost i saw was all it was making

I have did a boost leak test 3 times and the last time i put about 20 psi into the system and didnt hear or feel any leaks. i have checked everything i could think of and what i have read other people have had problems with.

running gtir setup with stock turbo, new w/g, cobra maf, jwt ecu but im lost any help would be nice.

sounds like a leak, I had blown off a inter-cooler pipe once and thought I blew the engine up. It only would make even pressure or 1 or 2 lbs and that is it. I would start with Wolf tune. Call em up and talk to them about what MAF they chipped it for and have them walk you through it. They have good tech support.

the sticker on the front says 93 cobra maf.

on front of what the ECU? cobra maf

oh yeah sorry the ecu has a sticker on the that says what its tuned for. 440cc injectors, 93 cobra maf, adv timing and some other stuff

dude, it could be a 100s of things but is only one. does anything change when you unplug the MAF? Does it die, bump idle or what?

i haven't tried unplugging the maf....how would that make it not build boost? ill go try that right now and let you know

dies as soon as i unplug the MAF

that is what it should do, so check your piping or better yet check your hot pipe and charge pipe. the inlets which run to the turbo. I had a lot of carbon build up in my pipes one time and it would not boost for shit. If you see it then take some carb or brake cleaner and clean that stuff up.

i did that today i took all the pipes before and after the IC wiped them down with a rag and put them back on and boost leak tested, didnt hear nor could i feel any air. ill clean them with carb cleaner tomorrow and post again.
