How do I know if I had a governor spring kit installed?
My power seemed to top off @ about 2200 RPM before. I could free rev it a little higher, but I was never able to get much power above that. I was hoping to just prolong the power curve through ~2800RPM before the governor started defueling..
Ok, so I adjusted the idle screw and now the idle is proper, about 750 in park.
I tried sliding the AFC housing full forward and I did not like the outcome. I tried sliding it full aft and everything seems much better. However, max boost seems to be ~15PSI (boot fitting capped shut) and no smoke (very clean). I then adjusted the star wheel to full forward to attempt to build more boost and it *may* have helped a little but the difference is not that noticeable. The truck drives fine now, but seems to have a little more power down low and a little less in the top end (15PSI vs 19PSI). I still need to play with the smoke screw a little to limit the pre-boost fuel, but that is also accomplished with one's foot for the time being.
I am a little confused.
What is the adjustment to build more boost/fuel-more in the higher RPM's?
*edit* the GSK kit seems to let it free-rev up through 3k without issues, but I have not pushed it more than that without valve springs.
