I have had this problem ever since my recent build. Only fuel upgrades I did was an airdog2 and ported fuel rails. When I get up around 50-55 the TC will lock and the truck will start bouncing or bucking. It will smooth out if I let of the throttle or once I get over 60mph. I just switched to Spartan so I could monitor a bunch of stuff. It is really bad on the 310 tune. It seems during this time FRP will swing bad but other than that FRP pressure is stable and holds fine at WOT. I have no clue what's going on. Any ideas guys?
