alright in the last two weeks i got both my pyro and my EDGE EZ installed. i got the best price around from Chris at 4wheelcustoms.com. the question is do the EZ's for the 600's only have 3 levels? i know there were some other levels on the other EZ's. i have been cruising on level 3 which is 75 hp and 150 ft/lb's. if i get into it the pyro shows 1350* quickly and i have to lay off before i really get to see what it does through 3rd.
