Can I ask a question? How do you get a Shelby GT350R passed 220? Mine will only climb to 208 (yes I've modded the tranny but am not to the level of adjusting individual gears yet >_<) So, what can I do. It has everything I could find for it. NA tunes, Superrcharger, filters, headers, exhaust. . . weight reduction, custom transmission, clutch, flywheel, driveshaft, suspension, diff, . . . engine rebuild. Any ideas? Someone up here said they managed theirs up to 230. I don't care for controllability, I'll deal with that on my own. I just need to get it up to 220+.
