Just thought I would let you guys know that I and a buddy at work who specializes in VE's have found a design for a governer spring that we think might accomplish what you guys want to do. It is a "hybrid" spring and involves modifiying a variety of pump components to make it work. We will have to use some equipment at work to do it and hopefully we will have something by monday morining so we can give it a shot on the test bench.
Old Smokey, I would be interested in giving your modified AFC pin a try on a test pump. At least this will be a known spring that you have noticed a power increase from. I will compare it to the stock pin found in your truck to see if you really are gaining anything from increased travel. Please reply back ASAP so that I know if you are still interested and I can get an email address from you so I know where to send my mailing address.
