Tow/haul with nelson tunes?

Just thought about the other day, a lot of videos I watch the guys have the t/h button on...does allen do any kind of "race" mode or anything with those? I'm still extremely happy with my NP tune...amazing!

Unfortunately, there isn't anyway to do this, the button uses the same timing and a/f ratio regardless. The only change are shift patterns and firmness.

i know what your talking about,i used to have it on my 2000 5.3

instead of manually shifting,just put it in 3 and press the tow/haul button,it would drop to low 1 automatically,race ready just punch it and shifts on it set points.

i used to like pressing that button lol instead of dropping it in low 1.

Yea I used to have fun with it, but I like romping on it from 30 and hearing the tires chirp and when it hits second and they chirp again haha. I can't wait to take it to the track now that nelson tuned it, hoping to get a 3000 stall by then also.

My tune has different shift RPM, PCS settings, TCC settings, etc. with the button on.

No idea. I have my purge on my tow haul button. More than likely like above said. It shifts quicker and a little firmer with t/h turned on.
