I'm running a trd supercharger with 9.5 nst pully and a header, and my tc idols rough. Do i need to get some kinda charge cooler or an emanage??? help!

 

better discription of "rough idle"?

 

every time i dips below 1000 the car shakes. its hard to start when its cold too. theres alittle backfire when i shift from 1st to 2nd too.

 

check all your vacuum lines first...does the car run like crap under boost also or just during idle?

 

it only shakes at idol, top gear it runs like a dream so i figured its not a timing problem. i was thinking the heat soak from my header was doin something. i checked the line, but im gonna check them again. am i lookin for boost line to be totally off or what?

 

at the shop I used to own we had a pre-production tC with the TRD Supercharger. It idled funny b/c there was no fuel management.

But your probably does sound like a vacuum leak. You could also use a AFC to help with the tuning or just step up to a emanage if there is something out there.

I know AEM EMS for the Scion tC is out soon. That would solve every thing...
Complete engine management...

 

i have a brand new afc2 for 190 shipped

 

it was a vacuum line, at that t fitting by the bpv. thanks, tons o help

 

woudl i need a piggyback if im running a custom fit CAI with the TRD S/C?
