Does anyone have any experience with plugging in chips designed to increase hp and gas mileage? I'm currently looking at something from autochipsdirect.com. Do these things actually work? Is there a trade-off or downside to doing this? What about reworking the air intake? Is this advisable with the chip. We have a yearly vehicle inspection - will this be a problem? We're talking 2007 Tacoma, 4cylinder.
Thanks for the help!
