Hey sal I went to the track this weekend and the temp was allot cooler and the truck should have run great, but it didn't. My best pass of the day with a one hour cool down was a 12.89 @ 105mph. I'm thinking that the truck is loosing allot of back pressure with the new dynomax bullit mufflers.

So, I'm putting the bassani cats back on the truck. I really think this was the reason for the 3 to 4 tenths I lost. The wether was great and the 12.89 was the truck gutted.

what do you think. could i need to calibrate the chip for the exhaust again. I would love to know while I got the bed off the back of the truck, HAHAHHAHA. ((you'll see in two weeks when I get done.))
