The ECU retains previous check engine lights, so just pull it with a voltmeter and look it up in the manual.

when im driving daily i never get over 10psi but when i get on it and as soon as i get past 125 mph my boost starts to go up from 10 psi to 13+psi so i let off. not wanting to blow the engine im running an open down pipe and K&N filter "boost gauge" free mods ' rest is stock

Or you can borrow someone's datalogger to capture the CEL code and display the malfunction.

with the open downpipe you are probably overrunning the wastegate. It doesn't do it city driving because when you are doing longer highway runs the motor is underload for a longer period because of the longer gears. what is with the quotes around the "boost gauge" what kind of gauge is it?
