BIG NANA said:WE got the dyno runs done tonight. The sheets will be posted on Wednesday. The real eye opener was that when we did a top speed run, we found that there is a speed limiter that keeps the speed to 160mph at 6000RPM in 5th gear. We are going to get rid of that this week and reset the redline to 6300RPM.
The NOS runs were good. The NOS added 140 ft.lbs, and just over 75 HP.
The tuning has really helpped with getting the truck to run right at the top speed for that one mile distance.
BIG NANA said:Got it on Ebay, had to cut it down to fit on the tonneau cover, if your not running one, then it just bolts right to the bed, I like it. I think it adds some stability at high speed, but some of my crew think I'm full of ... well you know!
