2007 F-150 SCREW. Only things not stock is Gott's mod & LT265/70R17 (up from P255/70R17). Everything else is completely stock. I live at 7,000' elevation.
When I bought the truck new, my salesman suggested I run 85 octane which is contrary to the owner's manual. He said they seem to run a little better at higher elevation than the recommended 87. So I ran 85 for about a year. I tried a few tanks of 87 for about a month, and it started coughing & sputtering when pulling grades or fast acceleration. It just ran like crap! I even changed brands, but that didn't help. I switched back to 85 & it's been running great ever since. We just purchased a 19' bumper pull toy hauler which weighs in around 8,500# loaded. Truck running 85 octane handles it pretty good, except for some steep hills at 8,000' ~ 9,000' elevation. No sputtering, but r-e-a-l s-l-o-w! with lots of downshifting. That's my history. Now, I'm thinking a Gryphon with custom tow tune might just help get a little more power to pull the TH. I'm not against running a 87 tow tune & using 87 octane fuel, but given the history, is 87 going to be the best way to go? Or will the bad experience I had running 87 repeat itself? OR (this is what I'm hoping) will the Gryphon with the 87 tow tune improve the performance of the truck so that 87 won't be a problem like it was in the past? I have a few other questions, but let's start here first. Your help is greatly appreciated! ~Frank

Well, I just got off the phone with Bill - Great Guy! If you can't get through the first (or 2,3,4,5 ....) times, keep trying - it will be worth it!
So, from the information I got from Bill, here are some of the answers to the above questions. Running higher octane than the vehicle is designed for (w/o a custom tune) will not help performance & may actually hinder performance. The owner's manual calls for 87 octane, but at my higher altitude, atmospheric pressure, etc, 87 was actually killing performance. According to Bill, a Custom 87 Performance tune and a Custom 87 Tow tune is really all I need for my driving habits & altitude. He went on to say that I can still probably run 85 octane a lot of the time because of the altitude. I will switch to 87 octane when we are getting ready for a camping trip. I asked about running 85 octane at lower elevations? He said you can't even get 85 below a certain elevation! I now remember our last trip to Mesquite NV, elevation ~1,000', 87 was the lowest I could find! I just never made the connection, but everything he said started to make sense. So when traveling to lower elevations empty or loaded I will be okay. I just placed my order for the Gryphon with the two custom tunes I mentioned & kept the Stock 93 Performance. Thanks again, Bill! ~Frank

Glad to got to talk with Bill and he was able to help....
another thing I'll add is that on step inclines in mountain driving when towing there's a few of us that use second gear to pull the trailers up those nasty hills....Using second gear will help minimize the shifts and keep the tranny at a constant temp...
