Hi, i am considering of getting a preve cfe. I've been doing some research (here, autoworld, random google search) and found that there seems to be some reliability issues. but it seems that they are getting less and less, which is a good thing. The "in" thing right now about the preve is the remapping of ECU/TCU. I wonder, since they are remapping the preves which are already on the road, will the new preves have a remapped ECU/TCU from the factory? or do we need to send in for remap after getting the car.

Btw, which offer is better, 2k rebate or 3yrs free maintenance?
