hey guys..... I was just curious on the cobb boost left/right and map boost readings
left and right is pre throttle body banks and map is intake manifold?

my current readings are left/right 22psi and map 19psi. any reason for the difference? what should I be watching. I noticed the map cobb reading is accurate as the oem boost gauge.

thanks for any answers and input guys. just a bit confused on variable readings and which is the actual boost of car.

btw car is fbo e85 stock map sensors, intercooler, intercooler piping.

I haven't see an issue like you are having before. All 3 map sensor should be really close together UNLESS you don't have you throttle open all the way.
