Hey everyone. I own a 1989 Ford Ranger XLT 4x2 2.9L V6 5 speed stick. I was wondering if you guys know anything about performance aftermarket chips designed to increase horsepower and fuel economy. I don't know anything about them, and the ads just put up numbers that look too good to be true. Could you guys tell me a bit about them? Would you recommend them? Thanks.:thumbup:
