What I would like to know, is if there is any engine programmers on the market anywhere. I'm not talking about a chip that you stick in the computer and you get what you get, but a plug in and configure parameters type set up, or something like we've seen a lot of in the diesel community, an on board adjustable series type programmer. I haven't been able to find anything yet that 'll do what I'm looking for. I'd like it to give me more power and not murder my fuel economy.......is that possible? My diesel wound up with about 3-4 mpg better (when I behave) and I can still blow a mustang GT's doors off (when I don't behave). But of couse that engine is a differnt animal entirely.......Thanks in advance for any help!
