Okay guys, I don't want to start a flame war, but I could only find spotty information and arguments on the topic of Hypertech programmers before I bought mine so I want to post a review and real world numbers now that I have mine installed.
My truck is a 2000 7.3 4x4 F250 quad cab short box with 201k miles. The only real "mod" I have done to the truck is the WIX DIY air filter/intake mod, although I've had my share of problems because this truck sat for 3 years I've learned plenty by replacing the injector cups, glow plugs, glow plug relay (the upgraded unit), fuel bowl bleed valve, steering box, outer tie rod end, shocks etc.
I have plenty of other toys, so this being my work truck, I've decided to take the mods slow, and that fuel mileage is the most important thing as I historically drive my work rig 40 to 60k per year.
I have a close friend who has a 6.0 with the SCT and loves it, but the more I read about the SCT, it seemed it wasn't the best choice for the 7.3. Also I know most of you prefer the multi-position chips for the 7.3 but I wanted something easy that would also improve my fuel economy as Hypertech promises like crazy as I'm not really into major performance mods.
First lets cover fuel mileage:
I drive a lot of routes randomly, and historically they would all provide slightly different (but consistent for the route) mileage counts because of "hillyness" etc. Here are the numbers for the route I drive most often. This route includes:
* 18 or so miles to the interstate from my house in stop and go city driving
* South on I75 from exit 104 to exit 38 (in KY)
* 4-5 miles in city driving
* Turn around and come home, so the same route backwards.
This route is very hilly on I75, and round trip, with no stops at any gas stations is 183 miles. I mostly drive 75Mph on cruise when I can, but often times have to slow down a few times for traffic or trucks going up a hill. For my hand calculations, I wait for the foam to die and fill up until the fuel is almost spilling from the filler neck. I have a bed cover installed and am usually hauling 500 or so lbs of equipment under that cover and driving with no passengers.
Average Before Hypertech, in the summer months, with no additive:
15.3 Hand calculated
*Using GPS mileage
16.1 on the lie-o-meter
Average After the Hypertech on Stage III, (two trips this spring so far, one day was 72, the other was 83 degrees), no additive:
20.1 Hand calculated
*Using GPS mileage
22.1 on the lie-o-meter
YES, THAT'S RIGHT, I DROVE A 7,200LB TRUCK FOR 183 MILES ON 9.1 GALLONS OF FUEL! FLAME ALL YOU WANT, IF YOU DON'T BELIEVE ME I'll TAKE YOU ON MY NEXT TRIP AND SHOW YOU MYSELF. FYI, it was 9.2 gallons on one trip and 9.0 on the other.
That being said, the damn thing runs like a scolded dog now, and I get nice (but not too much) poofs of smoke when I lay it down. It def accelerates much faster as the first time I hit the pedal all the stuff that's been in my cubby holes and over my sun visor for a year went flying all over the truck. Spool time is very quick now.
Only had it programmed for two weeks now, I know Hypertech says not to worry about your EGTs with their programming, but I'll be installing gauges next week to make sure I don't melt a piston, and am keeping my foot out of the floor until then.
Let the flaming begin........
