JDM PRO M - Stage 3 Performance Chip With Firmware Rev 6.0

This is a stage 3 JDM PROM performance chip for your vehicle. I bought it brand new from the factory less than a year ago. This one is so new and upgraded it’s as simple as plug-N-Play!! I tried it in my 09 Subaru Impreza. It plugs into the OBD2 port and will automatically start re-programming your computer to give you a 40+ Horsepower boost, 30% better gas mileage, faster top speed, quicker acceleration, and  more torque. You plug it in and just drive and it takes about a week maybe two for it to reset your cars manufactured computer system, and default stock engine settings. I promise you will love the change in your vehicle 100%.
