i put a tst cr box on for a guy tonight and he drove it and everything was fine and then on his way home he said the check engine light came on and he done the key check and it came up with p0088 code. does anyone know what this is?

 

P0088 = Fuel Rail Pressure Too High

Not sure why the TST box would throw that code....
