Superchips Cortex 1950
Shooter04 I like your post as I'm into honest reports. I had a 97 Supercab 7.3 with 5speed manual and the 3.55s I'm told. All stock. 10pm in the evening I pulled up to the pumps and filled up, giggled the truck until it was full to the cap. It's about 60 miles from Eugene to Salem hit the freeway set on 65mph. Drove up and turned around in Salem and back to the same station (sets right on the freeway) and filled up again giggling the truck until it was full to the cap. 18.86333 or something outragious like that. Now at the very same time my brother drove his 99 Crew with the 6speed manual, 4 inch exhaust and some sort of special air intake and a chip of some sort. Well he got 17.5mpg. So that's my story. Chugging around in the hills and in Eastern Oregon bumping around at 1300 rpms and such I got over 22mpg all true! But it gets worse. My truck was stolen.
Now I own a 99 Crew, Shortbox, 6speed manual 7.3 and it is chipped with Superchips Cortex 1950. I DON'T WANT POWER I WANT MPGs! Tell me if the economy setting is best or something else. I a believer that pumping up the power takes years out of the engine....I'm 60 years old don't need to do 80 mph going over the pass pulling the trailer...55-60 is good for me.
Looking forward to hearing back...maybe I should take it down to a shop and have them tune it back to stock as I don't know how to run the tuner....I'm told it's set on 100hp over.
