That's what i'm trying to reduce on these Evo's. The response is nice, but the sensitivity makes it annoying on the street, and very dangerous on the track or even goofing around on some twisties like I found out personally.
Erics car had the Forge DV valve, Mikes has the RS. Erics car now has the stock MR valve with differential chamber.....still does it. Leads me to believe it not the valves, but rather the reversion in the plenum. I say this because Mikes car had this TERRIBLY on the way up to Moon for that d day, running on the meth map. Once we converted back to the original(and superb) street map from Justin the issue subsided drastically, but still remains. The other ironic part......all cars that seem do this have been cammed
Again...fucking with intake reversion. The math is the sucketh!
I'll let you know how it works out...
