Towing ?s and Issues
1995 F-250 7.3, I just pulled my race traler maybe 7800# loaded, to Vegas from San Diego about 350 miles. When towing in 3rd gear up a grade at about 3200 rpms the truck bucked a couple of times towing below 3200 was fine. After a couple of bucks the check engine light flashed so I quickly droped the rpm and all was fine. I could not use fourth gear on the grade as it would bog way done. Any thoughts on this?

I have but have not yet installed a Superchips power chip it is a single unit that you plug into the trucks CPU, is this any good for towing?

thx diego

This question belongs in the '94-'97 forum, where you put it. The moderator that moved it here made an error in judgement.

The HP peak for your stock engine is 3,000 RPM. You should NEVER exceed 3,000 RPM. All you're doing above 3,000 RPM is thrashing the oil. So slow down to 3,000 RPM and enjoy the ride.


Yeah, I know. The red line for your engine is about 3,200 to 3,300 RPM. But the answer still applies. Keep it below 3,000 RPM and you'll enjoy your tow vehicle more. I suspect your engine was "cutting out" because you were too near the red line, and the computer was "idiot proofing" your engine by not allowing too much RPM. But I'm not an expert on your older PSD, so hopefully some of the OBS guys will respond.

Guess you found the "red" line, huh?
