Last week I bypassed the FDC in my 1971 M35A2. Today I finally got to take it out on a test run to see if the differences described in several Steel Soldiers posts, would apply to my truck. The difference in hill pulling was simply unbelievable. Hills that made me downshift all the way down to third gear, could now be pulled in fifth. My EGT display now has become a vital part of this truck, as I now can easily hit the 1200 degree F limit. But that being said, the improvement to the performance of this truck is amazing. Thanks for all the posts on bypassing the FDC. The procedures shown were easy to follow. I highly recommend all deuce owners to install EGT gauges on their trucks, and then bypass their fuel density compensators.
