Im finishing up my truck and one of the things that I need is an ecm. the dropout that I bought didnt come with one. I just need the basic stuff to get started... 2002 lq4 with a 4l60e - I would also like the vats removed, premium fuel tune, no egr, etc. My question is, should I buy one from ebay and send it in to get tuned, or should I just buy one from one of the venders?? Any more options?? Thanks in advance, john
