chip scams
G Force and other companies that sell these so called chips that hook into mAS wiring,or IAT sensors are junk.Yes you will save some fuel but really I got slower 1/4 mile times.A simple 25 cent resistor 1.5k added between wire that goes to coolant sensor will advance timing and change AFR giving you .6 seconds faster times.
