Okay...my car has a 93 octane tune from VMP. Would I be able to spray say a 75 shot or even an 100 shot if I mixed e85 with my 93? Id get the car dyno tuned eventually. Im just seeing if this would be possible for the meantime.
You will more then likely blow your engine. Timing is to far advanced in a NA tune. Plus mixing e85 with 93 is not like mixing c16 with 93. It takes 30% more fuel when running e85 and the car has to be tuned for it. If you mix e85 and 93 you will run LEAN.
