Kind of like the title says. New '18 GT Premium Convertible A10. Did a baseline dyno and 2 weeks later dyno'd with an E85 tune as the only mod getting 40 more ponies to the rear wheels. Seems like a big gain to me. Does this sound about right? Less than 1k miles on the baseline and just over 2k miles on the E85 run. The only other mod I have laying around the garage are a set of Pypes off-road long tubes. Dreading trying to install them though. Lol...
