So, Ive been contacting a few of the reputable tuners in the GT500 community about future mod plans for my 2011 GT500. Mods include a TVS, pulley, injectors etc.
One of the tuners stated that AZ gas is shit quality, and that 91 octane tunes more like 87. Essentially, any gains of buying a Trinity TVS and 2.5" pulley would be ... ehh at best. Now, Ive never been under the impression that AZ gas is awesome, but I never thought it was bad enough that AZ 91 premium was considered horrible. Hell, Ive heard more shit about California mandated 91 blend being shit for performance than AZ gas.
Brands Im using in my Shelby are Shell, Chevron, Mobil, etc. Top shelf, name brand fuels especially on race day. Hell, come race day I plan on mixing 3-4 gallons of 100 octane in with the 91 to make 93-94 octane.
Is what im being told baloney? Anyone have any tuning issues traced to poor 91 in AZ?
