This is typical for 415 CIs pulling 20K pounds +. I would not go above 4,500 RPM. Some say the V10 is a high revving engine, but the computer limits the rpm to about 5,200. Try anticipating rises in elevation, and applying power in advance. If speed sags, us a lower gear. If you get to the top of the grade, you have it half made.

Maybe too basic, but when was the last fuel filter change?

Thanks to all that replied to my question...I think that I need to allow the V10 do it's job @ 4000 to 5000 RPM's.

Used to tow with an Excursion with the V-10 and 4.30 gears with a 5 star tune. GCWR was 18k lbs. it would climb any mountain I pointed it at. Never stopped below 50. Stock it was a dog. 3.73 and no tune and it wouldn’t get out of its own way on the highway and overpasses were ridiculous.

I now have a 2012 F53 and tow an Explorer. I haven’t weighed it yet, but I’m guessing 24K lbs. this thing is slow as hell. It’s biggest handicap is the poor tune ford puts into the PCM. First off I’ve noticed the drive by wire is very intrusive. I can hear that I’m not getting full throttle opening when I put the pedal to the floor, and I’m sure that’s what is what is holding it back in the hills.

We just went up I70 in CO over the Rockies, and then 40 into Granby CO over Berthoud Pass. That was a workout! Down to 35mph. Outside temps were 90’s and it never got over 217 on the climb. I also think these are under geared?! Mine has 4.30’s with the 22.5” tires. Even with the 5 speed trans I think it needs 4.56 minimum! My buddy went up in his 17 with the 6 speed and he was down to 25 and he was towing a Focus and is approximately 1k lbs lighter. But I’ll start with the tune first

Next year will be the 5star tune for sure!

This question is for those that have a Ford V10 in a class A. I have a 2007 Allergo 32BA with the Ford V10 that only has 36,000 miles on it & I took it to mountains of Western NC this week, and it seemed weak on pulling power, I tried to keep the RMP's below 4000, and at time's I was down to 40 mph, I was pulling a 2003 Honda Element...it this normal?

Story short, leave your speed control on and let her scream.

This is probably the best argument for a DP and for having the brute slightly more than idling at 1500 rpm while pulling your toad up 6% grades.

I know everyone says the V10 likes to rev, but man I just personally can't let myself keep her above 4k rpms for any extended time, it's just so.. well.. revvy I guess. When the hill is that steep, I manually drop it to a lower gear, keep it right at 4k and cruise on up. Not floored, just cruising along but not letting it upshift. Yup, I get passed by other folks, but I'd only save maybe 5 minutes on the day if I kept WOT instead of limited to 4k.

It's a big load for a smallish engine.

Yeah, I can feel your pain somewhat and even though it's said, that you can't hurt it and in fact the engine loves it.

I used to do what you're describing with our old coach and for having a GM with a tranny that wasn't made to handle a heavy toad. Not because it didn't have the power, but for the tranny wanting to overheat. Either way, low gear at 25mph takes care of it and yes, you might be 5 minutes late getting into a spot for the night. Oh my!

The V-10 has been torture tested by Ford and at various RPM’s. It will live all day long at 4K! Just let it work the way it was designed. Other than the very intrusive throttle by wire programming.

If it makes you feel any better, I regularly hang out near 5,000 RPM, sometimes for 15-20 min at a time. When pulling heavy loads over the mountains, I just lock in low gear (2nd on mine, which is equivalent to 3rd on the 5R110) and let it hang out there. Then when I need to ease up for tight curves or slow traffic, i immediately catch right back up where I was (usually 58-62 MPH). My combined weight is 22-25,000 pounds. I replaced the first motor at 458,000 miles because of a warped a valve seat letting it run lean after the fuel filter plugged (my tune contributed, but my tuner took a bath that same weekend so I couldn't go back to stock). I also had the Banks PowerPack on since around 120,000 miles. All other cylinders still had in-spec compression, and the cross-hashing was clearly visible when I scoped it! And my 4R100 is still original with 483,000 miles!
