Guessing I should go to stage 2, flash it, and see what happens.
Also having the issue of not having the cruise control work anymore...is that the car's way of being in 'safe mode' or something?

even catted headers can cause cel code P0420 as the ecu expexts a cat with the same charastics as the stock one and many aftermarket cats are different enough to still cause the ecu to think its got a problem. you can disable the p0420 in the stage 1 rom and it will be fine
