Stuttering on deceleration.

[snyper1982]

Here is the problem, When I am cruising on the freeway, about 75-80, When I let off the gas the car will sometimes stutter. It doesnt seem to do it all the time, only when my car is moving at a fairly decent speed. Any ideas on what the culprit could be?

Oh yeah, this is not a problem, but I am curious as to why you need a colder plug when running higher boost? Like moving from the BPR6ES to the BPR7ES. Just crious.

is it a stutter from the motor or from wheels/drivetrain

It is from the motor, it is like the engine stutters for a second, then takes off again.

check to see if your running rich which cause your stuttering

Is your BOV recirculated or is it venting? If its venting, this could be causing your stuttering since you would be running rich whenever the BOV opens.

You know what, I think that is it. I put a new BOV on cause my old one was leaking real bad, and I don't think I recirced it. Damn, I feel like a moron for not looking at that myself. You live and learn I guess. Thanks guys. I really appreciate it a lot.
