is the limp mode when a sensor goes off and it richens it for safety? Why are they so cheap from him?

Limp mode wont get you passed about 6500 RPMS, just as it states, your pretty much LIMPING it around I could only get about 4lbs of boost on mine, servo wasnt working
They are a used ECU, but trust me, in the situation that you and I are in, $500 for an ECU compaired to........$1300? aint that bad. Ill take a used one. He's a good guy to deal with

ok cool man, thanks ill give him a call. especially cus cat is backordered on circle ecus with no eta
Are all the '06's the "circle" box? I'm just wondering why you couldn't use any ecu with the '06 programming? What did ac put out for ecu's? Square, triangle, circle? are those right? Any more. Not trying to hijack your thread just thinking you might be able to get something else. I checked mine its a triangle, hard to do anything by tuesday. Good luck.

Cat couldnt get all the fuel parameters exactly the same, so they made 3 designs of symbols. Triangle, square, and circle. You just cant get the fuel parameters that close. The injectors go with the symbol. If you buy a different symbol style ECU, you have to change your injectors. Food for thought I guess, its a pain in the azz, but 05-06's to my knowledge all had 3 symbol ECU's. If I go to a square style ECU, im going to need the injectors that go with it 
technological Pain in the azz, but understandable
technological Pain in the azz, but understandableyea the mapped each symbol different for different injectors. What i was told is you have to run the same symbol your sled came with for evrything to keep working right.
