engine stops
wasnt sure where to put this but since the car is supercharged ....here we go. my car runs extremely well, driveability is excellent but here recently ive had a small problem with the car dying after running for a long time around 2000 rpm and then pushing in the clutch, the rpms drop and the car dies. this rpm drop has always happened but the car hasnt died the way it does randomly now. i have cleaned the maf sensor and it still didnt help.....any ideas?

I'm with Camper, sounds like a vacuum leak possibly. It kinda sounds more like the symptoms when a cam is searching for idle, but it wouldn't be that at this point. Was there a tune update recently? Maybe the idle was set too low?

idle normally runs around 800....ill check to see if i can find any vacuum leaks, but i thought that would have thrown a c.e.l.

What blower system are you running and what fuel mods do you have done. I'm partial to think that there might be something wrong in that area.

Yeah, the tune can stop the lights from coming on even when the code is present, all depends on how the tuner set it all up.

I pointed to a vacuum leak due to him saying it came on recently.

Yes, but it seems like it has been searching for idle for some time now, at least it sounds that way...

my car did the exact same thing when I fiddled with the deceleration fuel cutoff parameters, try disabling deceleration fuel cutoff if you cannot find another cause, and if that does help look at clutch fuel cut off, I would bet your problem is somewhere between those.
