I just has some injector pump work done on my P7100 IP, two of the delivery valves had bad seals. While the injector pump was out I took the opportunity to have 3K GS installed and I also had them increase the timing to 16 Deg.

Now I have a few questions and one minor problem.

The problems is, when I start the truck I must tap the fuel peddle or the truck will not start. Is this due to the GSK and is it adjusted wrong?

How do I know what stock fuel plate I have? (engine has 210 HP printed on the info label)

Should I see increased power with the timing set at 16 Deg and the GSK installed? I had the truck tested at the state inspection station before the changes and after, I got no change in WOT power. Would the power increase be more at a mid range RPM and not a WOT?

My turbo wastgate opens at 22 PSI, would I need to modify this in order to get more WOT power?


They made the timing change on the injector pump and not on the engine gearing, is this a good way, and how are they different? What does the increased timing do for me?

The truck runs great and is very responsive, I love it ;D 8) But I have not pulled anything yet!

 

Cant help you on the GSK but it sounds to me like the idle is set to low if you have to tap the pedal. This is a common problem due to low idle speed.

Idle too low i have to agree i have mine backed off and that was my resulting symtom. I am now just in the habit of tapping the throttle lightly to start the pig, and unless someone knows how to start it they have a heck of a time getting it started or running especially in the cold
