a fex simple questions about hypertech programmers
I have a 2003 F350 4x4 with a 5.4 and 4.10 rear end. I have added a k&n filter and a jba catback exhaust. First of all what I wanted to know was what are the best settings for my truck (I don't tow) and would neglecting to install a different thermostat as specified in the manual damage my engine?

If your not going to run the 93 oct tune, then you don't need the 160 tstat. The 160 tstat keeps the engine cooler and allows the tuner to advance the timing a little more. If it advances the timing and you don't have it, the knock sensor should retard the ignition before you burn a piston.

installed the tuning today, and drove it about 40 or 50 miles since then, and I'm pretty much happy with the lower octane tuning. The shift firmness is a really nice feature and the tuning gave my jba muffler a nicer sound.

by the way, would I damage my engine running the low octane or the OEM program by installing the thermostat? and would it even make any sense to do so? what I mean is, does colder temperature have an adverse effect on the life of your engine?
because I used to have an 84 Deville years ago that only ran without a thermostat, with it installed it would overheat. needless to say, my hard earned cash spent on a new heater core was useless...

Fords like a little heat, with out the 93 tune, I wouldn't recommend a 160 tstat. 160 holds the computer in open loop more because it always belives the engine to be cold. I don't know if it still holds true for the modular motors, but it's unnecessary to have one.

one thing, though, I just upgraded to larger than stock tires, and I do hear a bit of pinging when going up hills. should i return the program back to stock and just keep the shift firmness?

stick with the stock stat.....and go for the 93 octane program.
your mileage will go up slightly, mine did, and i end up paying like 3 cents more a gallon, after MPG savings, for the premium.

Maybe headers? or high octane? i don't know

The tuner is going to help out with the trans shifting pattern and allow it to downshift better when it needs it and also control when it shifts into OD and back out when it needs it. Much better than Ford's stock strategy. The higher octane programming will add that much more power to it. I think for the price, the tuner is gonna help the trans out, which will give you the best bang. I really liked my Edge Evolution I had on my 06 F150. It made a world if difference in performance (yeah, there are better, custom tuners available) I picked that one because of the display feature. It worked for me. Good luck and let us know what you finally settle with. If it doesn't work out, you can always list it and try something else. It's not like a major truck mod that's hard to undo.
