Anyone have a tune they created and wouldn't mind sharing it? I tried a 100hp tune but my tranny went into limp way too much on the low gears. Would like to get several tunes and learn from the comparisons etc.

Also what fields have you guys had the most success with? I would like to create a tune that is a little easier on the lower gears maybe a 40hp to 60hp tune so I can tow without any problems. But I would like to open up 4th and 5th gear so that when I am on the freeway I pass people with no problems :) I imagine hurting my transmission is less likely in 4th or 5th so that I can get away with a some added boost in the 100hp range.

Thanks

Its easier to linp in 4th and 5th gears then down low. That is where 95% of the limps occur is the 4-5 shift 0r 5-4 downshift or once up past 80mph

I don't have any tuning stuff LB7 wise, but you can make some noticable changes with the B0727 table.

1,2,3 gears will hold more power than 4 and 5.
