I recently installed a Rennline floorboard on the driver's side. I immediately noticed that with the new floorboard I wasn't getting full throttle when floored.
Decided to adjust this evening and found not only was the linkage in need of adjustment but I was missing some of the linkage bushings.
Adjusting the linkage is a good quick winter project and not very complicated. Highly recommended if you haven't looked into it before. I think I wasn't at WOT prior to the floorboard change, should be interesting once I get some new bushings and everything back together.
