And if it was breaking up, even with new plugs make sure you set the gap. Don't know what's good for SRTs though, .22-.24 with stock coils (~.28 w/COP) works on evos but its probably way off of what those things like.
Besides the smoothing though, its a nice looking graph, good flat torque curve that you can actually use.

It might also be the BOV, you're right. It's an HKS SSQV, I'll definitely check it out while I'm working on the car this weekend. Supposedly a good gap for these mods is .35 so I'll start there and see what happens.
The torque is a lot of fun, but this past week with all of the rain has sucked, haven't been able to have any fun
