| Message | If your question is, do you need to reprogram it for the 555's, the answer would be yes.  The AFC can help, but reprograming the ecu is the best bet. The turbos bolt right up.  However yu should look into some new downpipes when doing the install.  Might as well do it then. Not sure max boost on one maf.  But with the 555 and the AFC, you should be able to run some higher boost numbers.
