Weather permitting this week I will try to get in some new acceleration numbers since now I have the updated tune from 5 Star to go with the Dynatech 1 7/8 headers and Y-pipe. Was unaware that you need tune adjustments to go with the PMASS Intake too. This new tune is set on 87 Performance/Tow. Truck feels strong as heck, but also loud as hell. Definitely got to quiet it down. Also driving the truck now you notice a big low end torque hit when you put your foot in it.

 

Ford rewrote the pickup playbook three years ago by transforming its F-150 bodies from steel to aluminum—a bit more costly and more challenging to build and repair! !!
