Im running the Stage 2 AMS 93 Octane map on my EVO X MR. I have the full turbo back exhaust, AMS SRI, boost pill removed and the AMS pill added where it should be. Problem is when I get on it It has trouble shifting from 2ed to 3ed and the RPMs stay really high. (Ill try and get a video). What could be the problem???? I do have a AM BOV that im going to remove, I personally think thats the issue. Any MR owners out there that can help?>???

get a custom tune...

what is the AM BOV, i have the agency power one, is your 50/50 or full rec. i do feel the BOV make for issues every so often

Cobb just released a new update. Please download and upgrade your firmware and map files. Then if the issue is still there, let us know.

That is odd since we don't make any changes to the TCU it should not effect shifting performance. When you say it has trouble shifting, what exactly is it doing? Not going into gear, or switching gears or just shiting to neutral and free revving?
