I had the day off today which is a rare thing and thought it would be a good time to get my H&S mini maxx trans. upgade for my 6.7 cummins. I called PARLEYS DIESEL PERFORMANCE this morning and was assured that the download would be e-mailed to me within the next 2 hours. It didn't happen at all even though I paid them instantly and called them numorus times. They are refunding my $ now. Does anyone have experience with any companies who do what they say thier going to do?
