i have a forge dv, MR valve, and a stock piece. stock leaks a bit, forge flutters, and the MR stalls my car.
whats going on? is this just me that can't find a right valve?

 

Stalls it all the way out?

I have the MR Bov, and every once in a while, the rpm's will drop slightly, but I've never had it stall out completely.

 

Does it vent to the atmosphere? If so, do you have washers so that you can change spring tension? If so, try that.

 

Not saying you did this but are you sure the got it installed the right way. I have seen many owners with it backwords.

I have the MR DV on my car and have no idle issues at all. Car runs great in fact.

 

What other mods you got UFO? How is the car tuned (dynoflash, AEM,...)?

 

Perrin MBC @ 20 PSI, Buschur filter, thru-the-mail Dynoflash, and a Perrin cat-back. Pretty close to stock really.

 

What he said. Never had a problem with my MR valve.

 

the car goes either real close to stalling or actually does stall. Only happens when going uphill then coming to a stop. Or when im in a parking lot going forward to reverse forward to reverse. I have turbo back exhaust, dynoflash, MBC, AEM intake.
I put my stock back in and it doesn't stall but gets close sometimes.

 

could it be that my vac reading is too low? im showing 15-17 at idle.

 

I usually show 19-21 in of vac with AC off

 

i have a feeling that its something to do with my vac.

 

The only time I get a stutter (MR valve in) is with the A/C on, coming to a stop. The rest of the time it's fine.

 

even without AC on it happens. usually when i come to a stop quickly after climbing a uphill it happens. what does everyone read at idle for vac?

 

I have the MR valve and have the same issues whether the AC is on or off. It happens when you are taking off from a stop and step on the clutch real quick. I guess the stiffer spring of the MR valve either needs more vacuum to make it open, or the ECU needs to be slightly retuned.
