Towing Tune Question
I have a question about towing with the 87 or 93 octane tunes. Is there a limit on what you can tow with these tunes...or can you not tow with them at all? Basically I'm wondering if I should buy a custom tow tune to tow my 2000lb boat or is that not enough weight to make a difference?

i don't think that weight will be a problem for a perf tune if you have one. i have a 87 tow tune, but haven't even tried it out yet. 2 feet of snow here and i ain't got anything to tow:weeping: hopefully bill will clear that up for you.

Honestly I probably never would have even thought about it but my buddy put a hypertech programmer on his 7.3L a couple years ago and I remember in the manual it specifically says DO NOT TOW ANYTHING IN PERF MODE. I figured it might be ok because the gas tunes are milder than the diesel tunes(100hp).

I suspect you could tow a 2000#, low profile boat with just about any old tune.
According to Bill, the canned tow tune was really not designed for me either. I pull a 3600#, low-profile, HI-Lo travel trailer and Bill wrote a custom tune specifically for that job. I don't really know what the "cutoff" would be in terms of towing weight between a tow tune and a performance tune, but I imagine it would be fairly close to what you tow. I'm trying to figure out where the damage would come from using a performance tune for towing. Possibly, the transmission would be constantly shifting or the torque converter would be constantly going in and out of lock? I don't really think you damage an engine by "lugging" it now and then. Bill, of course is the expert here - not me. - Jack

Where we run into a problem with heavy towing (2500+) on a performance tune has more to do with cylinder temps being slightly higher because of the slight modifications to the fuel curve. I wouldn't necessarily say it does any "damage" to pull in a performance program, it's just not the ideal situation. High performance applications are leaned out slightly to achieve good top-end power. Tow tunes run a little richer for improved low-RPM torque and lower cylinder temps under sustained heavy loads. Of course, there are shift changes and timing changes but that has a lot less to do with it than you'd think. Anyway, as you've already guessed, 2000 to 2500 lbs is about the limit for a performance program before I'd switch to towing. Hope that clears it up a little.

Very nice response, Bill. Makes perfect sense and tells me why we have towing tunes to begin with.
Thanks for giving us the "expert's" opinion! - Jack |

Almost seems like I know what I'm talkin' about, eh?

Well that clears everything up...thanks Bill. It's good to know the limits. I'll be ordering custom tunes soon enough...87 towing will be a must.

When I ordered my Gryphon I got a tow tune since I tow a 4000# trailer that really bucks the wind. Initially the tune wasn't "pulling it's weight" (I kill me), and Bill reworked the tune and now I have better response, more power, and increased gas mileage. Unbelieveable customer service! You will be very happy with a customized tow tune from PHP. Bill most definately knows what he is doing!

I can tell you that I do not have a tow tune because I might tow something twice a year so its not worth it.I used my 87 performance tune and towed my buddys 96 f150 4x4 up to the sand dunes on a car trailer with no problems.I was safe with it though and set the gryphon so I could see what gear it was in and whether the torque convertor was locked.I also did not floor board it ever either but was still able to tow 70-75mph going down the highway about 200 miles.I think the weight was around 7,500 pounds I towed.I then unhoocked the trailer,beat the hell out of my truck all day on the sand dunes,then hooked back up to the trailer and towed his truck back home.Thats a Ford for ya.
