I ran 15.40 best at 1000 miles. See my sig below for the best time. I have the internal "pipe" cut out of the airbox, right below the air filter element and Mobil 1 synthetic oil in the differential. 2WD, crew cab with 5400 miles for the 15.15 run. Houston track is at sea level but it is friggin' hot and humid here.
I have a drop-in K&N air filter on the way and will do further dragstrip testing when it gets here.
