Marine engines have a whole different set of requirements than automobile engines. They are designed to run at a set rpm for long periods of time. Unless you have an injector pump that is capable of keeping up you will see no gain.
Nice looking rig. :thumbsup: Never seen a shortbox ext cab 8 lug gmt400. Maybe I just never noticed... although once I see those holes in the bumper I will give atleast another look or two.
Have run bosch standard injectors and the Kennedy diesel reman high pops. Very little time on the Kennedy injectors so no comment. My 95 runs strong on regular bosch injectors. I went with the Kennedy high pops cause the ATT enjoys a bit more fuel.
