I’m still having the in-gear, engine surge issue; for some reason the computer thinks I have 13.9% throttle engagement only in gear with my foot off the pedal. I’ve replaced everything to do with the drive by wire but the main computer. I am about to remove the TPS from the throttle body and give it a thorough cleaning, but it’s tons better than when I first bought the truck and the MAP sensor replacement fixed the throttle lag upon takeoff.

Always been hesitant by not buying oem products, but it's working perfectly.
