Hello everyone. New to the forum. I was a long time Corvette owner that recently bought a 15 GTR. Was wondering for the money is a FBO 93 worth it. I don't want to run E85 b/c its a pain the ass to get your hands on where I live. I have currently on my car a Midpipe, cat back, Harman motive 2.75 cold air intake and a Cobb accessport w/Tcm with a pro tune. Car put down 510 whp on a low reading Mustang dyno on a 90 degree day at 18.5psi. An I going to feel a big difference if I go FBO 93. Thoughts?
