I have the same problem with mine since going SD and have wondered about this to. My stumble is in the lower rpm just as you tip the throttle in. I didn't expect it to drive this bad with all the threads I read about how good it will be. Its great above 2500 rpm. Mine is different in that its a Procharger.

same here I thought it would be near stock manners...mine stumble about the same as yours right at throttle opening it's not real bad just alittle annoying...I guess it's the small price I will pay for a high horsepower street car...

I have a SD tune on mine. It has never drove better, no stumbles, nothing!
Brent at EPP did a really good job on my tune.

well if you run over 83 pound injectors and an m6, your going have some drivablity issue. If get an auto you won't notice it at all...by the way I got 160's and a FAST.
