yes, Sumit Tunes my car, really simple mods, 3.0 Whipple, 3.0 upper stock lower, 2 inch headers, 1700idx injectors, tapped triple pumps, E85, I run Ethanol one R for overkill on knowing I have good fuel in it to lean on. all of the other normal supporting upgrades. factory front seats, rear seat delete. car is crazy heavy and me being 270lbs doesn't help.
