LFowler: Most everyone who has or had a 95/auto/160 realized quickly that when towing it couldn't get out of its own way. When not towing it wasn't much better. You could tweak the star-wheel and play with the timming but you were still on the bottom end of the food chain. Things didn't improve much until the 215 pump came out. It was a dramatic improvement with fuel flow and better injectors.
What can you do? We have a shop full of dodge delivery trucks and service trucks all with diesels, 94's thru 98's all 12 valve. We've experimented with all sorts of parts and combinations and we've come to a few general conclusions that hold up pretty well and offer consistency you can rely on involving the 160/auto or 175/manual combinations.
#1 - Gauges are a must. Boost and EGT as a minimum.
#2 - A #6 or #10 plate. The #6 will cause you to start thinking about a transmission upgrade, the #10 won't right away but will become an eventuality.
#3 -
Free flow intake air filter of some kind. The stock filter "sucks".
#4 - Free flow exhaust with minimum restrictions (4" is a good start).
#5 - 3k GSK kit. This will alow your engine to use more of its upper range power rather than defueling too soon.
#6 - Bigger delivery valves in the pump (181's, 191's if possible). The stock dv's are inadequate for any real towing power.
#7 - Set the timing. More fuel means more heat. Advancing the timing (16. 5 to 17 degrees) will decrease EGTs and make that fuel more useable at mid and upper range rpms. You will lose some power on the low rpm end.
*8 - Bigger injectors. 215's , 300's will stay fuel efficient and be less costly than bigger injectors. Fuel is expensive don't just dump it out the exhaust pipe.
*9 - The more fuel you start dumping in the cylinders you will eventually need a bigger turbo to use all this extra fuel and reduce EGTs. Remember: More Fuel = More Heat. More Heat = Bad, Need more air!
Its no more complicated than this. Or you can jump out there and get a 215 pump About $950. 00 rebuilt/exchange and not worry about fighting with the 160 pumps problems.
Hope this helps.
