I have a 97 ex with a b18c5, and I was wondering which one of these I should go with, my friend is selling the aem and I can get it for a decent price, it is brand new. I have one friend who has a vafc on his prelude and uses it for vtec changover, and to lean his out it helped about 2 tenths in the 1/8th. Uberdata is something new to me, but I have acess to a rom burner. I would need to buy an ecu however. I may turbo my car on down the road, but it would be at least a year, as I would do internals and all. Which setup would be best for me and why.
