IP tune for more power!
Ok so I have this "Fuel injection pump adjustment article" but I read if you turn the pump it will advance the timing of the ip moter and get more power but I cant find out which way to turn or how far to turn? Any ideas!
Thanks
Thanks

That article does not adjust the timing, it adjusts the max fuel setting.
Did you read the first paragraph real close?
Copied from the article.
It isn't really difficult to do, but I recommend not messing with the stock setting unless you have a pyrometer. It doesn't take much to overfuel a stock naturally aspirated engine, often with disastrous results.
With that said, in increases the fuel, out reduces the max fuel rate.
In being clockwise, out counterclockwise.
With fuel settings the usual reference is flats.
A flat is 1/6 turn or one flat of an allen wrench.
A flat makes a considerable difference in how much fuel is injected at max throttle.
To change timing, you loosen the three IP mounting bolts and rotate the entire injection pump.
Whole different process.

Idaho when you are pulling a long hill keep the rpm's up in a lower gear if need be. Even with stock fuel settings you can over fuel and melt her down. When she puls down and you drop a gear you really need to be able to accelerate if your holding it to the floor your egts are climbing even with stock settings turn the fuel up one flat and your compounding this. What kind of exhaust are you running and how many miles are on your ip.

If you have that many miles on your Ip and it has never been replaced it may be getting weak. If you have 1.5 miles on the exhaust it WILL NOT PULL TO EVEB CLOSE TO IT'S POTENTIEL period. If you have 175 thousand miles on a stock muffler it is likely full of suet and half stopped up making it way worse than the sorry state it came from the factory in. If you have not cut the soupbowl out and ditched the junk exhaust I would not even consider turning up the pump especially if you have to pull long hills.
When I was young you had to know someone to let you in a truck because you could melt a motor on the very first hill you came to if you kept your foot in it. Now with computer controlled fuel systems any idiot can get a job driving our idi's operate on the same princaples as the old school trucks.

O 
So thats what a pyrometer does takes its temp! I see ok I need to settle down and make another run up hill and the idea is to keep my rpm up!
I hear guys saying they tow 8000 pounds and have peddle left up hill makes me think somethings wrong!?
HMMMM NOTE TO SELF GET A PYROMETER LEARN HOW TO DRIVE TRUCK!

Oh gotcha cause if i dont force the shift the truck will do it anyway due to loss of speed so i force it early to make it easy going up. so thats bad to do? the hills in question is a long hill say about a mile long not steep just a good grade. I just want to cover my bases
I am thinking od off and keep it under 2800 rpms when towing but with no load od on and I guess floor it!?
need more time behind the wheel!
