Tuned my GS ute today...thanks to Simon from Extreme for tuning for the flash tuner and the tune. If you have an Xr6T/F6 and are thinking about what car will be next...just get one of the new supercharged FPV vehicles...you wont be sorry shows the new Coyote supercharged 5.0l Interior with leather option is nice ...Stock power, to be honest it felt like an NA V8 and looking at the dyno sheet below you can see the boost was as low as 3psi up the top. This new supercharged 5.0L is a weapon to say the least. 350kw atws (on a heart breaker Mainline dyno)...no other mods..just the tune.
