milehigh, hows things in colorado? i cant wait to go up elk hunting next fall....

your not the 1st person ive heard claim better results from lvl2(87) over the lvl3(91+) tune.

i havent even tried out my lvl3 yet because i like the lvl2 so much, and ive had my gryph for abt a month or a little longer. I dont plan on using the lvl3 much at all either because as far as im concerned the benefits will be offset with the additional price of higher octance gas.

as for mileage, idk what ur getting but im getting 16.5+mpg rt now with 33's, trying to get up to 17. the best i ever got w my 5.4 was 19mpg, before i got bigger tires so i think my mileage is just right for my setup. i also drive 80miles a day so i thought id throw that in for comparison(but you are at a much higher elev. than me). on the lvl3 i think that some gas could actually be wasted. dumping to much into the injectors to fully utilize. but that's just a suspicion. Bill would be able to provide a btr explanation on what the lvl3 tune consists of.

that brings us to the tranny issues. You will see btr mileage from lvl2 over lvl3 because the lvl2 tow tune has lower shift points. ive been noticing that running lvl2 im almost always in 4th gear, thus getting higher IMPG's. this is more beneficial for mileage than a tune that lets you 'wrap-out' each gear further/longer,with higher shift points. the principal here is to get into higher gears(numerically) faster, and increase mileage.

as for your hard shifting, unfortunately idk what to say. if u have the shift firmness adjusted all the way down and your still having violent WOT shifts, let off or ease back a bit and let that baby shift. then get bk on it.

i do this sometimes to get into higher gear faster instead of letting the tranny 'hang' for longer. By the same token, there are times when my truck loses speed/power gng up long hills. i dont worry abt this...the alternative is a quicker downshift and less mpgs. this is why i like the canned lvl 2 tow tune so much. when i need it power is def. there, in the meantime im getting good economy.

hope this helps and keep us posted on the hard shifting issue. peace
