what is happening, some kinda cut Options

[dingy]

ok i have a 98 eclipse gsx slightly modded . Intake, boost controller, hard pipe,type S blow off , underive pully, k&n you know the starters i am still running 15 psi of boost. well i was leaving work when it was just starting to really get cold in dec. well I let it warm a little bit and started to take off i noticed it was running real good i went through first gear about 4 k and went to 2nd and was at about 4 k again and boosting a little over 16 psi then the car just got real quiet and fell on its face then lunged forward and then it fell again and then finally started to resume normal driving again. well i thought that at first it was because it was so cold that i was able to make more boost because the dencer air. so i turned down the boost a little back to 14 psi and i havn't had it again.

well I just got a big T 28 to replace the T25. I started to think will i have the problem more and more and what could it be. Was it spark blow out well i checked the eridum plugs gapped at .29 there ok so maybe it was fuel cut that i don't know. I have not upgraded my fuel system at all (Yet). so i asked my buddy who has the same problem all the time on his 95 talonTsi> He gets the surge at at 12 Psi and he has a upgraded fuel sys. He also has more mods than i do as well. what is this problem that i had, and my buddy is constantly getting. I am afraid i will get it more often with the bigger turbo. I need to do somthing to stop this befor it gets as bad as my buddies who cant understand it either only it doesn't do it all the time. It"s an intermitten kind of problem. All i know its can't be good on the car . Please what is this? is this common when starting to build a dsm

Even tho a chipped Eprom is a great remedy for an annoying fuel cut issue, it's completely un-necesary for a lightly modded car...I mean cmon!

I wouldn't start buying a whole new $300 ecu just to run for a couple more months in the cold with out hitting fuel cut, just keep the boost lower and your foot off the gas more often....

Once the weather is a little bit nicer, but not too hot, you will be able to bump the boost back up with almost no worries of fuel cut, until you start hitting the REAl magic number that the ecu will start cutting fuel, which is probably in the 18-20psi range on that 2g mas you have...Anyway, by the time you are running that high of boost you will most likely ( I hope) have fuel mods and a tuning device to help the ecu see less air from the MAS (SAFC) so fuel cut should be delayed once again...

So I wouldn't doubt you seeing fuel cut
