I ran my 05 Lariat SCAB this morning since we finally got some cool weather. I use a G-TECH performance meter and the truck clicked off a 15.67 at 89 mph. 0-60 rang in at a healthy 7.67 sec. I have an edge programmer, K&N CAI and bassani cat back SIDO. That's the best it's ever done. Previously it ran a 16.23 at 85 mph but that was on a 90F day with 95% humidity. I looooove cool weather.
