I have asked this many times and no answer. I put the 370 injectors and 4k gov kit on my truck at the same time. It has a lope that gets really bad from 1200to 1800 when going slow and not pushing out the black smoke. if I drive it like I normally do, It does not do it. I heard sometimes the 370's will do that on a 160 pump and I was wandering If that was it what is the fix? thanks <br>DM01

Did you also get heavy duty valve springs? I know TST Products recommends them when you go with a 4K GSK, but I'm not sure how that would affect your 1200-1800 rpm problem. Just a thought.
