My breakover spring and the pin it contacts on the throttle lever shaft were really wore down, my spring was starting to bend backwards(just slightly)getting ready to break. So I ordered a new spring from a Diesel Injection Shop in Nashville, marked everything so I wouldn't lose my indexing, took it apart and welded up the pin and ground it back to a concentic shape, and installed my new spring and all I can say is WOW, my truck is alot more pepier I had put a 16cm turbo housing on it and that helped some, but not what I thought it would do, but the trucks always been in need of some extra power, Guy at the diesel shop said I was losing some but not enough to make a big difference, well was he wrong, I cannot believe what that done for the ole truck, and I can really feel my new turbo housing on there now, just telling a small experience... .
