I noticed that my avg econ was hanging in the 17 - 22 area, so i calculated some miles and compared my rpm and speed and realized that my tire circumfrence was wrong. It was 2340 something i think, and with the canned tune it was 2550, I did the math in the manual and came up with,, 255 x 70 x 0.02 ( 357 ) 17 x 25.4 ( 431.8 ) both together 788.8, and x that by the 3.1415 and got 2478.0, going to re-program that in the morning.
I'll definitely be testing out his settings. I was just wondering if there was any improvements I should make prior, but since its my truck and I have my driving style, I suppose I am the only one who can answer than question lol.

Darren, please look at my Q & A on the Custom Options menu. Any number you see in TS or GR in the Custom Options menu is likely to be "bogus". Does the 2478 you calculated account for "squish"? If not, subtract about 3% or about 74 mm from it and use that as a starting point.
You ARE NOT going to see the values for GR and TS that Bill put into your program if you open the Custom Options menu! I know this doesn't make sense, but, it's the way the software in the Gryphon functions. If you bypass the Custom Options menu though, you'll load correct TS and GR values (unless you've put in new gears or wheels since your tunes were written).
And, Bill tried to write tunes for you based on his understanding of your needs. I'd give them a chance. Oh, and I think the WOT shift points and max RPM Bill used was fine too.They're only about 100 above my settings and I asked for tunes that would save gas and give me good passing performance, not peal rubber off the tires from a standing start performance.
