Should i use a tuner?
 

I have a 2001 2WD Screw with 120k and a partially slipping first gear. Ive heard a lot of good things about chips and would like to put one on my truck. Would the benefit of slight customization outweigh more wear and tear on an older truck?:help:

I'd be weary of chipping/programming anything that's already has existing mechanical problems. You run chances of it being more pronounced and/or making it deteriorate faster. Just my 2 cents.
