Hey there - I inhereted this beast from my pops a couple years ago. Finally saved up the money for the 4x4 conversion and fresh paint and body work. She's always ran great but after getting her back from the conversion she feel's like a slug. Planning on having her looked at soon by Sin City Diesel out here in vegas. I'd like to get 3k gov springs, have the fuel plate adjusted, and the fueling screw set / possibly timing set to 16°. I want her to be reliable above all but she's not boosting nor putting out any black smoke like she used to. I think she tops out around 18-20lbs where are before she'd hit 30lbs with no effort. Not that I'm after smoke but its something I noticed it doesn't do anymore. And possibly not going into overdrive, but this is a 3k built 47rh so not sure where to start. Anyway when browsing under the hood I noticed this wire...curious if anyone has any input what it's connected to and or what the heck its for. If you made it this far - thank you lol. This whole thing has been a journey. When she's back from paint in mid october i'll post some photos. 285/75's tomorrow after work!
