Im curious who has had their truck dyno tuned, how much it cost and what it entailed. What setup did you get tuned? I have a Speed density TPI system I am going to get dyno tuned here shortly. I got a chip burned from Street and Performance, and it isn't right, never has been. I get code 43 which turns out to be a faulty chip, so I am just going to dyno tune the thing. There is a place we deal with will do it for 475. Then after I see where it makes its power ill re gear it, since my powerband changed after installing the TPI. Any input, comments or questions?
