Liberty GT Spec B Verso tuned by Sean @ Allstar Garage last night. Big improvement on the bum dyno, no more throttle hesitation or stutter. Will be driving the Lib for a couple of weeks before the next stage, Phat dump pipe and AVO TMIC then re-tune. 

Liberty GT Spec B no performance mods except HKS Panel Filter, Resonator removed. Retained Stock Boost of 1.1 bar but kept it from dropping off and A/F ration of 11.2 raised to 11.7
