pcm adjustment

[kglowacky]

When I had my harness done 3 years ago the programmer/Harness modifier asked me for info on my truck such as rear end ratio. a/c etc. I gave him all the info and I assume he programmed it into my pcm. Well come to find out I gave him the incorrect info on the rear end ratio. I have a 3.70 and he programed a 3.07. When I contacted him 3 years ago I asked him to change it, He replied drive it and see how it works. Well, I tried contacting him and he doesn't respond, I live in Houston and been asking around and can't find anyone who will take my pcm and reprogram it with the correct ratio. Does anyone know of anyone who I can send my pcm to that can do this. I can't believe it can be that difficult. I don't want a 700 dollar tune just a ratio change. Or am I asking for something that is does not affect my daily driving or can't be done.
