91 Octane

Car feels great kinda sluggish starting out at that 2k rpm but as soon as boost hits it wakens right up and feels just as fast as my last set up - stock turbos/stock inlets on MHD 2+ e50

91 octane plus vp additive for 7 points

After O2 .98 corecction

We were running 91 octane fuel with a vp fuel additive that added 7 points of octane. The car ran 13.21 before adding the down / charge pipe and tune. After adding tune the best has been 13.35

Happy with how the car feels overall, just wondering if I could get a bit more power out of it or is my stock fuel system already a limiting factor?

**Stock Tune** States that CTS charge pipe might be culprit, car makes whining sound and not sure whether if it is from the turbo / engine area or the transmission
