I have been running 93 with meth inj. and a fmic.On a 408 with t88 rearmount with 9.5 to 1 com. and around 15lbs of boost.I talked to one of the sponsors about doing a sd tune and they recommended going with race gas and getting rid of the meth.Was just wondering what you guys are running for fuel.Or if you are still running meth inj. with race gas.


Thanks

It highly depends on what your tuner wants to run and what you have avalible around you. If you have 110 from x brand, then run that. Either way a big name fuel will be a good consistent mix to run at high boost levels.

Are you guys running 110 leaded gas or are you mixing it with 93.I was told the leaded gas was bad for your car is that just a myth.I have a couple choices In brands Sunoco 110 and Turbo Blue 110.

It all depends on your requirements of what your running.

Any 110 in the tank will be better then none for aiding detonation.

Leaded fuels are not good on 02 sensors and will cause then to die, vp makes a higher unleaded octane called ms109, it is about a 105 pump octane rated (r+m/2).

Leaded fuels tend to be cheaper compared to the high octane unleaded.

When you plan on running high boost (race track or just getting at it), stop by the house and dump in 5 or so gallons of the good fuel.

With a Sd tune you can do say 10psi is tuned in for pump 93, and 15-20 is tuned in for 110+.
