Greg,
My testing says you are right. The 385's I've done respond to the 2 step. If you are running a P/G combination the 15/8 might help by rocking the Tq curve down a little. Always lost MPH and high #'s on the dyno with them. A collector change to a "Too big" helped, but not enough. didn't respond to a merge. the big 2 step did show something with the right merge on the track.
