My SCT tuner thread.

Well I filled up today...mileage is only up to 10.7 mpg.
And I'm worried about my transmission. The new shifts seem to heat things up quite a bit. Much more than I'm used to seeing.
I'm going to adjust my TV cable this weekend and see if that helps. Otherwise I may have to remove the tune.
I know there's a tranny issue. It shifts late into 2nd and 3rd (at low speeds) and not into OD now until I lift the pedal. I had this issue before but the SCT exacerbates it...the truck wants to be driven harder. The shifting issue is a mileage and tranny killer for sure.
So I can't blame the SCT...and as far as power goes, the difference from stock, especially on the highway against the ever present Oklahoma wind is amazing.

Today was rather interesting....
I went and filled my tank with 91 octane, which is pretty much what you can get for premium in this area.
I noted that my mileage had JUMPED on the last tank. I recorded an IMPRESSIVE 11.4 mpg! Fluke? Or did removing my bug shield drop my drag co efficient?
Anyway, after putting over 21 gallons of hi test in, I loaded in my 93 tune and took and took a test drive.
And then came home and loaded the 89 tune back in. Reason being the dam motor pinged like a &8^%&76798y%%4! So much for that. It may have had a bit more uummmfff down low, but not enough to warrant keeping the tune.
It seemed like the tune was set for about 40 degrees advance that was right now. Not what I would've have done with an old school mechanical distributor.
However, I would be estatic about a consistent 11.4 mpg city mileage, almost a full mpg over my baseline.
