I recentally made a 100 plate for my truck and put back everything in the stock location except the starwheel (I put it forward alot). The truck would only smoke after I would "pat the gas" or under hard exceleration at first, which is fine with me. I notice a big seat of the pants difference. Well since then I got a hair up my butt and decided to slide everything forward to get everything I could out of the simple modification I did. I really didn't feel anymore powerful at all, almost like it might of lost some but more than it did before the plate modification. And now it doesn't smoke under hard exceleration much at all. Is there some thing that might need to be adjusted? Does this sound like the governor arm needs to be adjusted? I haven't done this yet only because i'm unsure on how to adjust it. I've searched and found many cut away pictures of stuff that looks very helpful but it theres not a arrow or something similar pointing to screw/part that needs to be adjusted. Which nut needs adjusting? Red or Yellow. Thanks ken.

 

The yellow is the one you want. Here's a write up of it on PDR's site.
