1996 OBS No Pulling power
Ok went ahead and put in the TS 6 position switch. Helped on power of course. With a 24 foot gooseneck it pulls ok till I hit a hill. Then it seems to lug hard. 1150 on the pyro in 4th is no problem... it is an automatic. It will make about 9 psi of boost lugging in 4th. If you down shift to 3rd and spool it up it will make 16 psi all day..... Now put this same trailer behind my 2000 F-250 and it does not even seem it is behind the truck on the same hills. I tried it the other day and my 2000 did not even come out of 4th and was gaining speed on the same hills..... Any suggestions on some way to make it get a little more power in the ole 96 would be appreciated.... Thanks Wayne

It did not pull with a crap before when it had 410s either.. It just doesn't seem to want to accelerate in 4th if you load it much..... He change the gear to help fuel mileage.... against what I told him.. but you know some people think they have a better idea.... this truck ran better before he had the 7.3 replaced due to a couple of bad cylinders...

my 95 manual with the ts chip vs my 01 automatic with the chip pulls pretty close to the same. you wouldn't think it, the 01 is so much smoother and you really think you are outpulling the 95, but i've been loaded with identical loads and trailers, and i look in the mirror and the ole 95 is hangen with me! the 3.54's will kill your power and also if you didn't change your odometer gear (i guess they got a gear, i never changed ratios on my fords), you would be showing a lower mph then you really are going so that might make you think it's not pulling as hard maybe??? i do know the power delivery is way different with both my trucks. i think the 95 would pull a dam tractor trailer load but it seems like it doesn't get up to speed as quick as the 01. idk???

As for the speedo issue I checked it with my gps and it is only 2mph off. I also pullled my trailer with the 96 then went back home and swapped to my 2000 and ran the same road. I just had to so as to have a real comparison. My issue is that the 96 will not go ahead and make boost in 4th gear and trying to accelerate with out downshifting when with the same trailer and load my 2000 goes ahead and gains speed ..... just wondering if anyone had any ideas ... i appreciate all the replies sometimes its easy to miss things ... so thanks again

I think you are just comparing two different trucks... They will never equal eachother... There is a difference in gears, the OBS ones are too small. The SD is heavier. Gearing per gear is different. Turbos are different. Injectors are different. Is the SD chipped? If so it's making more power... See where I'm going with this? Way too many variables...
