I hope I use the right terms, anyway it's just happened to me with my 87 perf tune while driving uphill with 55mph (cruise & not) I'm just like loosing power and then gaining back (idling high then low and so fort). I just talk to Crystal and patiently waiting for the reply with my concern.

Is anybody experience this? If so, how do you resolve it? Now I'm on my stock again need to use my half full 87 octane fill. Planning to fill next on 91oct and install 91 perf tune. But I hope they (Troyer) can help me solve my problem on my 87 tune, and I know they will.
