Chasing a bit of information, BA Mk 11 XR6T ute 4 speed auto, some minor mods, but goes exceptional to a certain point, then cuts Xforce 4" dump, 3.5 system. PWR intercooler, SS induction bigmouth, F6 under headlight intake, K&N filter, larger injectors, Xede processor, bosch 144 fuel pump. Hits Boost cut just at gear change? But if you are going hard to overtake, it gets to about 150, and sounds just like drops a couple of cylinders, and cuts the engine. Been in the tune shop, only running 10psi, so conservative at 375RWHP, but they have trouble controlling the boost, and say it is the boost control in the ecu? Any thoughts.
