Absolutely. I'll turn you on to my tuner.
A simple pulley swap and more mojo...easy peasy. I'll give you my number and share whatever I can. I run E85 full time. The tuner also provided a "flex" tune so if you want to swap between the two you can. The only thing about E85 is that you consume 30% more fuel but it's cheaper so the rub is it readily available in your area.
My TrackHawk has the same motor your TRX would have. I pulled the blower in the driveway with some friends' assistance (the blower is a pig as it has built in cooling and well...MOPAR), swapped to a smaller pulley for added boost (you need an extractor I would gladly loan you), shorter belt, bigger injectors, a cooler thermostat and a tune/calibration that you need to "crack" your PCM (control module) to use. I use HP Tuners for software and run VMWare on my Mac Pro so I can run Win to use the tuning software.
You'll void the warranty but warranty shwaranty.... I've run a 10.3 sec quarter mile at ~132mph and I pushed her to 187mph at the standing mile (Texas Mile) a couple of weekends ago....weighing 5617lbs with my arse in her. Coefficient of drag 1.0...hahaha. Stock catalytic converters and exhaust. I could do a lower pulley / damper swap and pin the crank and make more but I'd have to pull the cat's which I don't feel like doing as it's my daily.
Vroom vroom...
