New to pcm tuning

I have tried to read as much as possible on the subject of tuning. I have a 2500HD that is looking for a little more grunt. I'm seriously looking into Nelson. My dilema is for the long term reliability of a vehicle with a tune. The pick-up has less than 10,000 miles on it and I plan on keeping it for a long time. My concern is with the TM. I understand that if you take it out you can increase useable power and possibly some better mileage. However, isn't the TM what protects the tranny and give it long life? I don't pull very often, but when I do it is a heavy stock trailer loaded with about 12-14,000 #'s. If I eliminated the TM I don't think the tranny would like that, or am I wrong? Why would GM "detune" there vehicles if there is no problem with a mild custom tune? It would seem to me that better mileage and more power would be a huge selling point for them. Maybe I just paranoid, but I'm a stickler with maintainace and pride myself with getting alot of trouble free miles out of my vehicles by keeping them stock. Anyone out there have a pick-up with 100,000 miles on a custom tune? If the mileage truely does increase then that should easily pay for the tune's initial cost I would guess. Does the elimination of the TM give the increase in mileage? Also if you keep the TM is a tune even worth getting?

SWDoodle,

If it helps, I can't think of one 80e that has broken on a mild modded HD truck. These transmissions are very strong!
Ask, bud8fan, he had a HD, with turbo and no TM, stock trans and it never missed a beat.

I can understand why GM puts in TM, but they do put in way too much in my opinion.

hope this helps,
allen

Thanks Allen. I just want to do as much rearch as possible before jumping into anything. If I was only driving up and down the highway I wouldn't be concerned, but pulling heavy loads is where I get nervous having the TM taken out.

Also, the tune that GM puts on stock vehicles has to work on all of those vehicles around every part of the country, high and low altitude, scorching and blistering cold temps. It is a one tune fits all situation.

If you have a 4l80e then i would say GIVE HER HELL!
