I'd also say the MPH's are higher than the ET's, suggestion possibly you're not hooking good. (this would make the 60' slower and ET's)
As others said more combo info may help. But I would try a set of slicks if allowed to run them. If not, what is your launch RPM or how you launch it?
Engine seems to be making good power just not getting it all to the ground I think.
