Very weird problem, feels like fuel cut.

Hey guys, I recently Upgraded to a small 16g, everything was fine for about two months, it was a total difernt car, it pulled really nice, but now when Im boosting it feels like fuel cut or thats what I thik, I turned the boost down to 13 to 14 lbs and it's still doing it, I had it at 15lbs with no fuel mods, I just now used a Snap-0n scaner and it came up with the folowing codes: P0170, P0505, P1103; The last code said: Turbo charge waste gate solenoid malfunction, What does that mean?? the first code didn't show anything. what should I do???

Thanks.

anyone, what should I do?

You boosted to much without adding any more fuel, oh and you have an idle code who doesnt.

id say get rid of he bcs and get your self a mbc

Does anybody agree with forcefed 95? if yes why?

I upgraded to a 16g also and i have a EBC and mine runs fine i do agree with the above comment bypass the stock BCS and Just use the MBC to control your boost...just as an add i no this is not safe but i have creeped up to 17psi to redline and still no Fuel Cut so i would do a Boost leak test why your at it to make sure that you dont have a leak make the fuel to cut off.

If you were running it off of the bcs, how did you turn the boost down without a mbc?

Well now, my car feels like crap when I hit full boost instead of going faster it feels slower, Im about to do boost leak test here in the next few days to see what going on. I hope there's a leak somewhere that than a blown turbo! Could the problem be the waste gate auctator?

did you ever do a vacuum leak test? what was the outcome?
