You will be on par with the meth N54's if you run the 100 octane race gas map. I doubt 100 octane will be readily available so I'd bring some if I were you. Terry Burger is signed up too so he can help you fine-tune if needed. Terry installed a JB on Jeef's Cobb-tuned n54 on-the-fly during the last Big Willow roll on event and Jeef ran the 100 octane map and totally transformed his car.
By the way your 335 looks like mine.
