I just recently installed my Jb4 along with my bms air intake and now have an engine light on along with a EPB light on is this normal or did I make a mistake?

In your picture you have a ESC light and an EPB light. Should have nothing to do with your JB4 and bms intake - unless you jarred a wire loose while installing either (but that should have caused the lights immediately).

Do the lights go out after turning off the engine and restarting? If not, it's dealer time.

Yeah the lights turn off after the car turns off and I uninstalled the JB4 and all lights turned off when I start the car but the engine which I sorta expected but should just try and more securely install again?

Did you get it working? Updates? I'm curious about the JB4

I did get it to work, the problem was the MAS Airflow Sensor which just had to be left stock not sure if that will be fixed in future updates or not. The results are very nice tho and I can definitely feel the difference from stock to map 1 and map 1 to map 2 highly recommend if it’s in the budget.

Cool man. Being that it seems to be the best bang-for-buck upgrade, I'm seriously considering it. Did you ever test 0-60 or 1/4mile times? Does map 2 require special octane or just supreme?

Thanks for your feedback.

I've been holding off on the JB4 until I get summer tires on. Are you on the stock Pirelli's? I've got the itch to get this but been holding off thinking that this car (GT) is so hard to launch just right, that adding more power will make it even harder to launch. I am often spinning tires just on regular starts (not full throttle). Hoping Conti ExtremeContact Sport or Michelin PS4S help with that. Aiming to get them next month. I just need the overnight lows to stay above 35 or so before getting the summers put on. (I have new wheels for them and will switch back in the late fall)
Any additional thoughts on the JB4 would be appreciated.
