Re: need help
I bet your RFL is leaking. Why do you have one if you dont have any other mods?

Re: need help
^I'd think so, but I think tal skinny's right in saying that it may be leaking... I mean open loop's usually cause the car to run rich between shifts and most require tuning in order for the BOV to actually function w/o problems...

Re: need help
Miles and maintaince?
Boost leak, whether from the BOV or somewhere else could be the issue. The BOV would cause rich conditions and backfiring possibly even stalling issues. How are your rpms at warm idle? Do they fluctuate or stay steady? When you say it lags at upper rpms, do you mean like an on/off hesitation, or it simply continuously lags?

Re: need help
I vote crappy BOV. The Turbo XS RFL BOV has been known to have problems every once in a while. I'd suggest getting an HKS SSQ BOV.

Re: need help
Or just put your stock one back on and see if the problems go away.
