Awesome numbers on the new G5 ISO - I'm sure if you throw E85 into the mix you can expect a good 12% power increase tuned right.
I almost wish I had dynoed prior to reverting back to stock from FBO.
I made 324whp/358trq on JB4 march firmware with only tune/intake. All else stock and using 91 octane.
Great job! Enjoy the new power!!
