brian whats up brother... I believe it is map 2 for pump gas.. I will confirm this when I get mine installed next week!! I am hearing they might flag cars that are tuned... hope this doesn't get us... LOL  |
Oh hey Buddy! Hows the car treating you? Well JB4 isnt a tune just a piggy back on the system. I dont think they will notice it if you just take it off the car before you bring it to the dealership. I Havnt heard anyone about cracking the ECU and tuning it. Have you done the break in service? I actually notice the car to be abit more powerful after the service.
