When playing around with the iPhone app PocketDyno+, I managed a 0-60 in 4.8 seconds. That was without brake-revving and with a bit of wheelspin off the line on my crappy 17" rfts... and I weigh 250lbs. Tank was 3/4 full too.
I think if I did some serious runs, I could drop down to 4.6, maybe.
I managed 4.7 with mine too on pocketdyno. Just needed a better launch and maybe the ppk could get 4.6. Over half a tank too and I'm 210. 18" run flats too.
Over all good flash tune for keeping warranty. Waiting for Cobb in the future. Far future at their pace!!
