Having problem with figureing out why my GST is stutering

[SlowdsmGST]

It seems that everytime I jump on it my car stuters around 3500 to 4500 RPM. I have recently replace ing. wires and spark plugs. I believe it is a coil but not sure. The car only does it once in awile or when I get on it and on happens when the car is in low boost. I have though that it was just plugs or wires because I have had miss fire in cyclinder 3. So now I am at that point where I am tired of spending money so if some one could help I be a happer DSM owner.

What kind of wires are you using and what kind of plugs? I had the same problem and i swapped out my plugs to the NGK Bpr7es and it doesn't do it at all. If your still on stock boost level then you should try the BRP6es. Hope this helps.

Boost leak test it. IF you don't know what that means, search for it.
