flat, yes I can program one for defaults. Update, I have 7 done thus far, so hopefully I'll be shipping them out Tuesday! To be on the safe side we decided to richen the maps up a tad to take into consideration the fact that most of you are now experiencing dense cold ass air. This is just to be safe, as we tuned these for 70 degree CA air, originally, and my primary concern is safety. What I strongly recommend to everyone is to go to a dyno and either A. tune it there, or B. send me the a/f and dyno results and I'll make you a new map for your particular weather conditions. The units will still net a very noticeable gain, but you can probably squeeze another 15-20hp by tuning them to your exact conditions. Another point to remember is that the full benefit of the tradeable maps will only be realized if you guys do just that, make different maps and share them. Ok that being said I'm heading back to the laptop to program the last 3 maps.
