I see all this talk about black bear proformance and wheatly and nelson tune ups. i have looked at black bear but couldnt figure out if they did them with my truck i drive a 1997 5.7L v8 k1500 4x4 z71 with 190K and i really wanna see the differance with one of these tunes, but i cant find out if anyone can do them on a truck as old as a 97 if anyone knows of someone that does please let me know i am still trying to find somebody and sending emails ill let you know if i figure it out

 

I think that wheatly will do it i really wanna see the differance is with it i know country09 has one from wheatly. if anyone can tell me what i should expect from this tune that would be great and my main question is how do you get it from them and on to your truck?
