Ok, so ever since my rebuild, my car has been doing some odd things. For instance, on certain days, if I rev around 5k or so and let the rpms drop, my car will die. And on top of that, I've tried the lubricants and had them reajusted, but my belts will not stop squeeling. And it's gotten worse, like to the point they sound like theyre about to snap. I also need to know how to cure fuel cut, cuz I think that's what I'm hitting now. My mods are:

-FPT28 Turbo
-3'' Apexi Downpipe
-3'' Tsudo Catback
-NGK plugs (gapped @ .30)
-K&N Airfilter
-HKS SSQV BOV

I think thats it. Thanks guys.

Don't forget all your stickers! ;)

Rewire your fuel pump--that should help with fuel cut. As for the rest of it, I dunno...

Does your car die when it's warm out? Or just in the cold? I know my car will sometimes die when it's this dang cold and I haven't let it warm up long enough.

Also, is that all you have for mods? You shouldn't be hitting fuel cut with just that I wouldn't think. I'm no expert though... If you are, rewire your fuel pump and see if that helps. If it doesn't, I've got a new Walboro 255 lp fuel pump sitting at home I believe... :)

Is your BOV recirculated into the intake or is it venting to the atmoshpere? if you are venting to the atmoshpere that could cause your car to die. I would suggest putting a larger pump in your car.

Yea I doubt you have a maft so Id say that the venting is causing the dieing.

Also you should upgrade to 550s, I have stock ones now and even at 13 psi in this cold I get fuel cut and my duty cycle hits 100+.

I just put in some 550s and should have the car up tommrow and well see if thats what the culprit was for fuel cut. IC pipes and the GM maft really open up the airflow

He has a 2g Peter, that is a whole different deal. I am willing to bet it is dying because of the vented BOV too. I would at least rewire the fuel pump. You are in pretty desperate need of a SAFC or DSMlink too.

To be honest, the BOV sounds like the problem. Because I only experienced the fuel cut thingy once I put that in. It is venting to the atmoshpere. But at the time I had my boost restrictor pulled out. Now it's back in, and I have to put in the MBC I bought. As far as it dying out, it mainly happens when it's cold out.

I'll get you a 1G BOV and you can give me the SSQV for my van.

Eat a dick Dane! jk LoL. I love this thing. :bounce:

Yeah, if you are venting to the atmosphere, that could be causing your car to die when it's cold out. Venting to the atmosphere isn't recommended under any circumstance and usually makes your car run like crap.

so to sum it all up.....

get a bigger fuel pump
do not vent your bov

I am sue it is the bov that is stalling the car. The same thing happens with mine sometimes. You are not calling fuel cut the jerk when you put you foot on the clutch of let off the gas are you? That would also be because of the bov. It is not fuel cut however. What boost are you running? I see no way for you to be hitting fuel cut on your setup unless you are running mad boost.

As far as your next mods go, get a fuel pump, 550's, and a SAFC along with a datalogger or dsmlink.

What do 2gs differ with fuel cut? I guess I didnt know the diff besides the 2gmaf being different.

Some cars fuel cut before others... I dont think I should be fuel cutting at 13 psi when its cold out. right?

I did wanna get a fuel pump. I just pm'd Jana about it. And I do want a SAFC...but I dont have the money to burn on one of them right now. Not unless I can find one for cheap.

nah u don't need an safc unless you upgrade to bigger injectors. A bigger fuel pump should cure your fuel cut all by itself.

But I heard that you couldnt just cure fuel cut. I heard it was in your ecu?

Fuel cut is basically the ecu telling you that there is too much air coming in for the fuel to support it. This is why you get an safc, to lean it out and fool the ecu into saying there is less fuel needed for the air coming in (metered air).

If you get 550s the D/C rises therefore the fuel cut limit rises too. If you get a bigger fuel pump that raises pressure which make the Injectors work less i think.

Correct me if Im wrong.

I am not sure about a fuel pump having much to do with fuel cut. Larger injectors dont even help if you are unable to lean them out. Larger injectors help you because you can "fool" the ecu by leaning out the mas reading. What boost are you running? Don't guess either. You may have boost creep bringing you to 20psi and hitting fuel cut. John had that a while ago on his 1g. For him, boost creep seemed to come and go with winter.

ok, i guess "cure" was a poor choice of a word to use. Fuel cut is not a disease or anything, its there to prevent you from running too lean and messing up internals. In your mod list you have a few things that add more AIR, but nothing that adds more fuel. So you've maxed out your fuel pump and it can not pump in enought fuel to mix with all the air you're shoving in there. So a fuel pump that flows more will make it so you aren't hitting fuel cut anymore. If you really really wanna just get rid of fuel cut all together, you can buy a gm maft and it allows u to shut off fuel cut permanently, but then that'll just allow you to run as lean as you want, and fuel cut just won't hit. So you'll just run as hot as u want, but u could start doing serious damage to the internals. And if you're not monitoring egt temps, then you'd have no clue that you are running too hot and just start ruining stuff. God im tired, sorry if this isn't worded to great.

Larger injectors dont allow you to lean out more.... it allows you to run more boost without maxing out your injectors.

I have the MAFT and the stupid switch that supposedly shuts off fuel cut doenst do shit.
