No, you most definitely should not be running a higher ethanol content in your fuel tank on a 91 tune other than the standard amount of e10-15 that is already in pump gas. The car will not run correctly and it will be dangerous for your engine as the dme will think you have full e85 in the tank. Tuning wise, timing, spark, and fuel trims are completely different between pump gas and full ethanol tunes. You would need to find a custom tuner like Cary Jordan, Paul Johnson, or many other popular tuners on this platform so they can make a custom tune for your specific setup.
