Mitch,
Did you test with a scan tool? Judging by the code you got it by using the HEC Dealer Test . That is the test using the LEDs from the odometer. Code 5284 is scan code C1284 Oil Pressure Switch Failure. It is not related to the Chip.
With key OFF disconnect the oil pressure switch connector and ground the contact on the connector. Turn the key to ON, if the pressure indicates normal your oil pressure switch is going bad. Common problem on these trucks.
BTW any codes captured using the instrument cluster has little bearing on Engine codes. These codes are for the proper functionning of the instrument cluster.

Hi r6raxcer & JMC,
Thanks for your response, JMC, as always, you have come to the rescue once again!
Knowing what the code represents is key to diagnosis, a retrieved powertrain error code (DTC's) will generally have a P prefix, ala P0605, etc.
This obviously has nothing to do with the Superchip.
It's a good idea for anyone who is either keeping their vehicle beyond the length of their warranty, or for those who are doing modifications, etc. to have a factory service manual and a good OBD-II code scanner. They will pay for themselves many times over the service life of just about any vehicle, and will allow you to do a fair amount of your own diagnosis, at the very least giving you an idea of where the problem is, such as whether it could be related to a modification, for example, as in this case.
Good luck r6racer!
