What is the best upgraded turbo and fuel option for FBO on 93 octane? I do not want to run meth and the car is a daily driver. I see lots of dynos and claims for ethanol whp records but the nearest E85 station is 45 mins away from me. I do have quick access to 100+ octane though. Am i really going to gain much by going to stage 2 over stage 1 twins on 93?
