Thanks for having ANY info about your car. Except for 3800 rpm.

Not really sure why you would need any info. Its a 2003 pontiac sunfire with a 42trim turbo on a hp tuners tune

If your looking at a tire to see if its flat do you ask what brand the tire is? It doesn't really matter what motor or trans I have. Its not those that is creating the problem

I think what Kev is asking is could the wastegate cause this? Nothing else has been changed and it wasnt acting up until he put the wastegate on. in which case the year engine etc doesnt matter.

Is it backfiring or afterfiring?

I think the point guys are trying to make is that if you want people to share information, they would at least like to know more about car, the person, if there's something different or special about the set-up that may be causing the issues etc.

If you have more basic information it really helps people from having to ask 20 or 100 questions to get the root cause. If you want to be 100% anonymous cause you're "super bad-ass" clandenstine, then you're looking at the wrong place for information. Everyone takes some pride in their ride and wants to be unique - but c-mon you have a boosted J - so do many others. The point is, you could share something and contribute to further the general body of knowledge and help those who are trying to help you.

So maybe your tial with the atmospheric dump is introducing oxygen into a hot rich mixuture causing the back-fire. Are you running open dump, or recirculated?

You seem to have all the answers so figure it out on your own... BTW, just a heads up, if you expect help from anybody with knowledge you may want to fill out your profile. Another pointer, stop being a know-it-all douchbag. You are a tool, probably always have been, and until you can stop being one, don't expect any help from me.

In all this time, you could have just told them what year/model/engine/tranny car you have, and what all you have done to it.

Now you have pissed everyone off, by being a douchebag, and I wouldnt be surprised if nobody helps your bitch ass.

Oh.... you're right. What's wrong is you have the boost set too low for the wastegate. You need to run at least 18-20psi. It might not stop doing it right away at first, but eventually it'll stop. Might need to hold your foot in it a bit a few times.

All this time, and even after making my original reply, I never even caught that the answer was so simple.

This is the PM the OP sent me... I have nothing to hide, so the PM is being posted and I will reply here...

To the OP, or CockFAG, or Kevin Roskosky (Whatever the hell you want to be called..) If you seriously need to ask me why you are being referred to as a "tool", read all your responses in all your threads... Stop with the attitude, show some respect, and maybe you will make it around here.... I have my doubts about it though....

Just because you don't know what could cause it cody star, you don't have to be a smartass and just try to be on qwk ln2's side because he knows more than anyone of us
