Tired of going up a pass at 40mph...

[ninty7pwrstroke]

Well since this is a chat thread, I'll shoot this out to you guys that have the knowledge and experience.
I have a 1997 OBS Powerstroke crew cab 4x4, auto, 4in lift, 4:10 gears, MBRP 4in back exhaust, AFE cold air intake, 275/70/18 wheels and tires. Truck runs great has 188K mileage. I just replaced all the glow plugs, and injector harnesses. Maintenance is up to date, new fuel filter and cleaned the FPR screen.
Here is what drives me crazy, When I pull our family travel trailer that is 30ft and weighs 7700-8000 loaded down, when I come to a hill pass I can start out at 60-65mph and then manually take off the overdrive at the first sign of speed loss. Then I just keep loosing speed and I shortly wind up at 38-40mph and sometimes having to pull down into second gear to keep her going!!. Maybe I'm just jealous of other newer trucks raving about passing people on hill climbs or having to slow down..Grrrr!
But I think I can do better or should be able to do better then 40mph...
So I've been contemplating spending the money for some stage 1 injectors, a TW chip and a Banks IC. Is this gonna help with my towing power? Or am I throwing my money away? The truck has tons of power alone, its only when I tow and go over hills that sucks. Flat ground no problem holding 60-62mph..getting 11.5mpg.. Thanks for any help guys.

If you have stock injectors then 35-40 on a grade with a load is doing quite well. I think you're on the right track with your upgrades, but add some good gauges into the mix.

yes for sure some gauges. Also if your running a stock trans cooler time to upgrade. its a cheap upgrade thats simple and ur trans will thank you. tony W. has some good tow tunes. I had Rosewood stage1s ( now have 2s) and Tw tunes in my OBS and have hauled very heavy loads with no problem. just have to watch that stock tranny with more juice in front of it. your on the right track.

id throw an hpop in the list as well.

how hard would it be to swap in the tranny out of a newer truck since they are a bit bigger and dont they have 6 speeds?

He's got an auto trans so a 6 speed swap will be a lot of work. It's a lot easier to go from a ZF-5 to a ZF-6. The auto trans in the SD's is basically the same as the one in the OBS trucks.

6.0 or trucool tranny coolers are probably the best bang for the buck.
