higher RPM's higher boost... Luggin in OD will make less boost than locking out OD and raising the RPM's...

Any suggestion of what I can do to hook up my ride 1996 f350 gas

 

to correct your speedo's, you have to reprogram your psom. there is no geear for them, it is from your your rear abs sensor in top of your pumpkin that reads a permanent magnet in your rear end.

 

my 95 doesnt make the boost in 5th gear pulling hills (or even 4th) like my 01 does in o/d or drivemy 95 might make around 15-16 tops winding it out, probably less than 10psi in 5th gear. where my 01 will make 20lbs easily on tow mode in any gear. but like i said, with IDENTICAL trailers and loads, my 95 isn't that far behind on the bigger hills around here where i live but we don't have huge mountains on the east coast like the west coast! put some 4.10's back in it, and it eat!!!

 

Your chipped powerstroke is only making 16psi?! Something is wrong.

I concur with the above though, downshift if you have to to bring rpms (thus, power and boost) up.

 

my chipped 95 is only making 16psi. chip may be messed up, gauge may be messed up. i dont care, the truck makes me money and i dont drive it anymore so **** on it!!! and it will run with alot of newer trucks, so i really dont think anything is 'wrong' with it.

 

well the 16 is low. but my 94 Powerstroke wouldn't do much better when i was towing.

 

Ya it's only running damn-near stock boost levels and half of what a chipped truck should be running.. no biggie :P

 

I wouldn't jump to the conclusion that anything is wrong... If you downshifted and gunned it, I bet it would make more than 16psi... Towing in 5th gear isn't going to bring the boost...

 

These aren't 5.9 Cummins that make 30psi at 1800 rpm. I have owned a couple obs 7.3's and they like to be wound out when they tow. My 96 was a 5spd and if it wasn't above 2k rpm it wasn't going to pull anything.
