I have had my '06 LLY since june and have yet to do any mods to it. Mostly because I do not see much on the market as of yet. I know I am not alone w/ this issue. I have been warned that if programers do come on the market to quickly for the current model year that they most likely will have little testing done and just be the same as the prior model year. I am looking for a unit w/ about 4 to 6 levels, say stock to 150hp. If someone can give me some info I should would be grateful.
