Hey y’all, I just got an AP and I have ridiculously high Fuel pressure PSI. I googled it and everyone seems to have like 43 idle. I have 400 at idle and like 1500 when driving.
When I took my car to the dealership about a month ago for a multi point inspection he said everything looked good on my car.

I'd contact Cobb and ask them. I'm left to wonder where in the system you are actually reading (not to mention what car you own -- what is the nature of the injection system, etc.).

Whether the pressure you are reading is artifactual or actual, your own dealer sees nothing wrong with the car. This is something that will likely be resolved with a phone call, in other words; it does not seem to be a case of a malfunction.

(Have you even modified the car?)

I'll bet you are reading articles on port injection systems and not direct injection and your car is direct injection.

1500psi on port injection would blow the injectors instantly.
