Default High DI Fuel PSI after CAI install

Had a CAI on my 06speed for awhile and my Fuel Pressure DI reading on my DH has always been around 1700 or so. Tonight I put on a SRI in place of the CAI, disconnected the negative terminal first, and started her back up. It seems the fuel pressure is going through the roof now, like around 3-4k at idle and up to 10,000 under throttle. Is this just part of the ECU re-learning process or is something jacked up? My AFR is still around the same as before and the STFT is about 3-4% under throttle. Any ideas?

Thanks

Are you sure it's not reading in kiloPascals? A few times I reconnected my battery without unplugging the DH first and it started reading all temps in Celsius and fp in kiloPascals.

Yeah BIG EDIT....I just went out and checked and I guess the DH defaults to metric...Switched to English and all is well...Add another reason I hate Europe and the stupid metric system. Cant people fall in line with the superpower?

Thanks Guys for the quick replies on me being an idiot.
