How much additional power by turning up the full power screw?

On a stock intercooled 92 160hp engine with the bigger turbo, how much power will I likely get by turning up the full power screw 2 turns? Would I have to worry about EGTs when pulling hard on mountain passes and the highway?

EGT's should not be a concern. You will gain some smoke and the HP gains will be modest, but it will help with the TQ. I would also turn the sstarwheel down a little in the AFC and re-adjust the fuel pin sim it is at it's deepest setting. Don't be surprised if you have to turn the idle down once you turn the fuel up.

Thanks. At the moment, I'm looking for a bit more pulling power going up mountain passes. I think I'm ok with the current throttle response around town (at least for this week). This being the case, doesn't the AFC and the fuel pin just help the part throttle and throttle response?

The fuel pin will help with overall fueling.

Deepest setting being the one that allows the fuel pin to extend out the furthest?

It'll turn a decent truck into a great truck.

I would install a EGT gage before touching that fuel screw.

On days with temps of 85 and above. I can hit EGT temps of 1150 or so with only a light car and trailer behind my truck on small hills. At cruise on flat ground with the same load it is 975. This is with the only fuel pin turned. My pump is all stock fuel setting as far as the fuel screw.

Look at my location also. This is in Indiana. "ALL FLAT GROUND" in my region. Your running in mountains with a heavy load. 2 turns on the fuel screw might cause problems.

Be safe and install the gage then you can dial the truck to your driving and conditions.

I was thinking that since the engine only generates 160hp/400ft lbs that it could stand quite a bit more fuel without pushing the exhaust temps too high. I know there are other factors involved.

I will be towing a jeep or trailer up and over the passes out here in Colorado. Usually accompanied by several other vehicles towing similar stuff. Pride being that insidious thing that it is, I'll probably want to have my foot in it so as not to let by buddies get away from me.......

Any recommendations on a temp guage setup? Where is the sensor placed?

Thanks
