I'm not a fan of JB4 piggyback types of tuning; I had purchased one but returned the unopened package for a refund. I'm also not going to the trouble and high $ expenditure of pulling my ecu and sending it out for tuning. BM3 and others will eventually have ecu tuning products to offer and at that time I'll be all over it. In the meantime I'll entertain myself by reading all the "when are they going to come up with ecu tuning" threads.
