The 60' time isn't real accurate to figure off of. I say this because an 11 sec truck may suck out of the hole and cut a 1.9 or 2.0 but pick up big time around the 330' or 1/8th and finish out amazing. I guess if it helps most guys running 12's are 1.8's to low 1.9's, not doubting your times at all, but I have a similar setup and I've managed a best of 14.7 on 28" slicks? That was on a N/A tune from nelson through the mail. Granted I had 3:73's at the time, but I can footbrake it up to 2800ish on the line and I cut 2.0x 60' all day. I also have LT's over your shorties and caltrac's...just curious what my trucks deal is and why it needs to grow up. Track conditions that day were 2mph winds from the back and about 80*.
