Nelson Tune?
#2
I just installed mine last week and I to had aHPPIII, ther is no comparison.I couldn`t get my truck to power brake with the HPPIII now I can powerbrake but from a dead stop I can burn tires at least 25 ft then it hooks up and goes.I got the 91-93 dual tune,torque management removed and my shift points beefed up, I have power all the way through the power band now.Allen really knows how to tune you should call him and talk to him you won`t be disappointed.

I don't have the tune but I've heard many good things about it. I'm getting mine done on the 12th though. What color is your truck? I live in Deer Park to. Maybe we can run em one day.
