What would happen if you get a KO4 Turbo and run it with the same ECU you have for the KO3?

Should run fine assuming the car is Pre2000 (DBW)

Default for a DBW car, error code central / pre 99.5 not much at all, the ecu will call for the same boost

thus only giving you a small improvement as the boost on a ko3 chip tapers off at the higher rpms to save the turbo from going BOOM! but the ko4 flows more efficently at a higher volume than the stock ko3 so there is more boost at the higher rev's

Default Charlie's right about the DBW.. NON DBW cars can.

Run the Ko4 with a Ko3 chip but Fueling might not be perfect. You would have to at least add a 5bar FPR to the mix.
