Stock looking stealth setup, stock airbox, intercooler, piping etc. GTX28's machined into -5 rear housings, twin 3 inch exhaust, Xspurt 2000's. The tune was pushed pretty hard to make that 500, but it made 480 fairly easily on e85.
@ Rear wheels on Trent's hub dyno, accepted to be on par with most of the local roller dyno's.
