so thats what that BOOM! im i got last night from you was huh? lol damn dave your havin all kinda fun huh :lol: next time just try low gears to hit the cells I dont think your gonna be hittin 130 in the 1/4

Youch, that really sucks. But now you can get a better driveshaft :) .
BTW, you should be able to "hit" the majority of your engines cells just by cruising and holding a gear then moving the throttle up and down, just do this slowely so as not to trigger power enrichment (open loop) or DECELN or DFCO (also open loop modes). Then for the rest of the cells just extrapolate from the known good cells. This is what I do all the time, and then for the high load low engine speeds that seem to get flashed by the scanner I just use trial and error. That area of the tune is all about accel enrichment.. and the high vacuum (engine braking) cells are just there for ****s and giggles. You can tune them for optimized gas milage or in Matt's 454 we went for the "Oh my G*D that thing is beastly." :D

FWIW we were only at 38% throttle position. :cry: Oh yeah, do not doubt my 130 in the 1/4...thinking about 20lbs on the 6.0 :twisted:

Well it was the tranny that blew up. It locked up and tore the driveshaft in half. It also cut my fuel pump wires, dented the muffler real bad and some other collateral damage. :(

Oh well....It's just the kick in the ass I've needed to put the 700r4 in.

[foff667]

so what size stall do you plan on puttin in that thing? Im thinking like 3200-3500 with the blower.

[badzracing]

2400 stall....I hate high stall surging.
