I have a DSM problem...please help!

[dsm4life04]

Today i messed up. My car is tuned to run at 2 boost settings, my daily driving is set at 11psi and with the flick of a switch i can run 20psi. Well coming home today i decided i wanted to run 20psi just for a short period of time and ever since it hasn't been running right. I got up to about 5000 rpm's when i shifted from first to second and second to third, then all of a sudden it didn't want to boost. So i flicked my switch back down to my normal 11psi and the car doesn't really boost at all anymore, in any gear. Also, when i'm sitting in first gear, the car almost wants to idle out, however it never does, it just goes down to like 300 rpms. I know somebody knows what this is, and i'd REALLLLY appreciate your help. Thanks!!

I hope you have an afpr too. Was there any smoke when this happened? Have you tried a boost leak test?

[dsm4life04]

Nah there's no smoke at all, i no i haven't tried a boost leak test but i'm hoping thats what it is, or something small like that. In my old gs-t the turbo j-pipe came loose and caused kind of a similar problem, but that was a stock turbo and stock injectors. In all honesty it feels like i just blew a hose off or something, but i have no idea where to start to look haha.

you blew a pipe somewhere

[dsm4life04]

Hardly a weekend ruiner. You can make a tester at for ~15 and test it out anywhere with a compressor, like your local Wawa where the air's free. Good luck, most likely a leak.

just check all lines and couplers...a line could even be cracked or torn

...and another vote for the boost leak test! Takes 10 min

[97TurboDSM]

if it takes you a weekend to do that then you should just give me your car.

yeah I definitely think you blew an intercooler pipe off somewhere. If that's what it is, make sure when you're putting it back together to spray some hair spray on the pipe and coupler before you stick it back and and clamp it down. That way, it'll be nice and sticky and won't blow out again.

you answered your own question man. If you think you blew a hose off, CHECK YOUR HOSES. I always carry a set of mechanic's gloves in my glove box for this reason. Sucks when you have to reach in between your turbo and radiator after boosting to put a I/C pipe back together and you keep burning the **** outta yourself cause you dont have sleeves or gloves.

I'd double check the intercooler couplers, then if that doesn't solve it go for a boost leak test. Anytime my car had boosting issues before questioning anything I just did the simple boost leak test.

[dsm4life04]

Alright guys thanks alot, i just got really concerned right away cause my car was running to perfection until this happened. I'm gonna check the intercooler pipes and a few other components and if that doesn't work i'll do the boost leak test. Like i said thanks a bunch...

97TurboDSM- For that reason alone i'll make sure it doesn't take me all weekend...however if it does than i guess the car is yours! Haha.

[Sberk06]

I'll speak on behalf of 97TurboDSM, and tell you that he would rather me have it.
