Difference between High-Altitude and Non-High-Altitude - Diesel Forum

Woody_PSD · 02-05-2008, 05:46 PM

I have already decided to buy a new F5, but I have a question about the High Altitude tow modes.

I am located @ 4200' ASL so naturally I am interested in the High Altitude Tow Modes, however I do travel to locations that are not high altitude locations (<4,000').

Can you tell me if there would be a problem towing in the lower altitudes with a high-alt tune?

I don't think there would be, but wanted to ask just to make sure.

i run at 7-8K' in flagstaff and the normal 80E is perfect.
but i am not sure about heavy towing

You will be fine using the high alt. tunes at lower alts.

What exactly are the advantages to a high alt. tune?
I live at 4000' and travel to and from less than that regularly, infrequently above 5-6000'. What are the benefits and or differences.

Thanks
James

what are the advantages/disadvantages to running LT275/70R18 on 2003 7.3 Power Stroke Excursion?

None that I know of. Just bigger rims, and more expensive tires. The tire turns out to be a 33" which is similar to the 285/65/R16 that is pretty common on most fords. Mine came with them from the person I bought them from, so I didn't put them on, I'm just living with them now since I have them and get the joy of buying new ones this month since the old ones are worn out.
