[QUOTE="ZoNiE, post: 1011489, member: 54000"] I'm considering one of these. We have 87, 89, and 91 Octane here in Phoenix. I figure I'll get the following: 91 Performance 87 Economy Towing - Not sure what Octane I should program for. I usually run 91 as I get 1-2 MPG better with it so the extra cost makes no difference to my pocket, and It seems to run better. My Trailer is about 6,000 lbs, and I tow into the mountains... Currently, I get an overheat condition in the high altitude about halfway up the rim from 5000 ft elevation to 7,800 ft elevation. It may have been due to a leaking radiator, which the dealer found when they replaced my Right side Head due to snapped off exhaust studs. We'll see this coming summer. WIth new plugs, @ 77K Miles, my truck is actually running much much better, and getting better MPG's. Now, some more questions: Should I get the SCT first or the Zabtec throttle body? One or both? Which is better? Do they basically give me the same results? Are the benefits of both additive? If I get the SCT now, and the TB later, do I need to get new tunes? [/QUOTE]
