Which puck do I order

[firemanwyo05]

I have an 04, the last digit of my vin is a 3, and the Manufacture date is 12/03. So which should I order, the 57, 58, or 59. What are some overall impressions about this chip; good, bad, what? Im trying to avoid having to rebuild my auto tranny thats why I want to stay in the lower power ranges till I can get the cash to put in a ATS

Thanks,

the 04s are a hit and miss on which one to get,see if where you buy it from can get you a 57 like its suposed to be and a 58.i tried 3 57s till i read on here to try a 58,iwas lucky my dealer is just down the road and i got them overnite till i was happy.i would get a ptreator instead of the puck if i were you,you will be much happier in the long run,as new updates are vailable you can get them,the tow mode is a nice tune for your auto,then later when you get some work on it load extreme and have some fun,i noticed a gain in milage and she runs very smooth on extreme.the engine doesnt have to work very hard to get going,egts are high though but thats the stock turbos limits
