Hello everyone. I'm new here but I've had my 1991 dodge cummins since it was new. I've enjoyed this pickup but recently I got a 25' travel trailer and it has had a little trouble pulling it. I'd have thought the cummins would have more power. So, I did some research on the web and increased the injector pump pressure a little. I only went one turn on the power screw on the back of the pump, turned the smoke screw (or whatever you call it) on the top CW 1.5 turns and clicked the little star wheel CW 10 clicks. I also rotated the diaphragm tick 1/4 turn to the right. It was set at 3'oclock stock and now it's at 6'oclock.
It has alot more power now but I'm worried about things like EGT. Do I need to get a pyrometer for what I've done? Or do I really not need to worry about it?
That was my main question. Now for a few others.
Will this increase in power harm the tranny? I've heard it's a weak link. Also, I really need to change my tranny oil. What's a good oil to use? I've never changed it before.
I know, bad but I want to do it now.
Is there a good cleanable air filter for this truck? I'd like to be able to clean it instead of throwing the old one away and save some $$.
Any other advise for my setup is welcomed.
Nice to meetcha! and thanks.
