[DrEdSrT4]

Hey guys anyone that knows anything not only bout dsm but shit in general. My friend just TRIED to install a Hallman boost controller on his car 2night.. after having it on for a while his car started to run/sound like SHIT.. started bogging, sperratic idle.. almost like it was pulling timing but not really.. i made him put ALL the stock lines back and reset his ecu.. but when he had all the stock lines on afterwards it was still running like shit... can some1 help me HELP him lol, get back to me asap plz i feel bad for him cuz he just bought it

sounds like a fouled plug if u ask me, that tends to happen when u raise the boost on cars

[DrEdSrT4]

ok ill have him change his plugs

yikes, i've never heard of that before. i have a hallman boost controller and it runs just fine. have him check out dsmtuners theres bound to be about 10 threads covering that exact same problem, i mean it is a dsm lol

was the boost controller actually working when it was hooked up? where was the mbc tapped?

[DrEdSrT4]

it WAS working.. tapped directly from the turbo.. and capped off the solenoids


EDIT: He replaced the plugs.. not NGKS cuz he said he couldnt find them but he got some other platnum ones.. his car still feels like ass. Once he hits about 5lbs of boost his car starts shaking and bogging?

[GotWhat?]

What was it set at when it was running fine?

[DrEdSrT4]

maybe 13lbs.. but hes got the car back to stock now, its just still running like SHAT

there are some replies to that thread, you should check them out and let me know so i can respond.

[DrEdSrT4]

yeah i know.. i think my friends plugs are still bad.. he ordered the right plugs and wires online.. he bought new plugs but the gap was like .37 or 38.. supposed to be like .3 from what he said, so i said that could be his problem also.. his rough idle went away but once he gets over like 5lbs of boost he starts bogging again

Many things to look at with a DSM. They operate much like our cars do. Although they dont use MAP sensors (use MAF - Mass air flow) they experiece full cut very easily. Even with a completly stock car, if the air is not right, you'll get fuel cut. It's easier on a stock car where boost builds slowly, but when you install a MBC, boost comes on a lot harder. Unless he is running a AFC or something to add fuel, most likely fuel cut is what you are experiencing.

Other option... check the IC pipes, specifically around the sidemount, they tend to come off a bit and make the car studder.

also, gap plugs around .25 and check the wires/coil pack.

.028 to .030

Get some ngk 7es and you should be set.

looking back sound like a boost leak, Intercooler pipe came off.

[DrEdSrT4]

His plugs and wires are coming tomorrow, ill let you guys know if thats what fixed it.. hes also got an SAFCII or whatever it is sitting right in the dash?

Sounds like an air leak after the MAF, where is he from? I'm in Union and can take a look if you want.

We are up in rockaway exit 37 off rt 80.. ill letyou know how the car is today after the plugs go in
