through research on this site, I've found the only thing the jetchip does for the tundra is to raise the shiftpoint a few rpm. my shiftpoint is already at the redline, so for most of us, the jetchip offers no serious gains. however, about a year ago I got interested in reprogramming the tundra's ecu, so I hit google and spent about two weeks looking up information on reprogramming ecu's. Only thing of interest or worth noting was a page where a guy posted some code on how to reprogram his audi ecu.
