p0443 is evaporative emission control system, purge control curcuit malfunction, p0449 is emission control system, vent control curcuit malfunction. p0449 is often a filler cap problem on fuel tank. try tightening cap

The code indicates a problem with Air/Fuel mixture, and it is very possible with the "chips" you installed, the A/F ratio the ECM sees is out of tolerance. As far as inspections is concerned, you may need to remove the chips and reset the ECM before you go for inspection.

The barometric pressure (BARO)
The manifold absolute pressure (MAP)
The intake air temperature (IAT)
The engine RPM
P0121 The predicted air flow and the predicted MAP combined are outside a calibrated range for more than 3 seconds.
Inspect thoroughly for any type of leak or restriction
Air leaks at throttle body mounting area and intake manifold sealing surfaces
Throttle body for dirt, debris, and coking--Refer to Throttle Body Cleaning.
Increase the engine speed slowly to 3,000 RPM, then back to idle.
Exit from the snapshot and review the data.
Observe the Mass Air Flow (MAF) Sensor parameter frame by frame with a scan tool. The MAF sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.
If the MAF sensor g/s does not change smoothly and gradually as the engine speed is increased and is returned to idle, refer to DTC P0101 or P1101.
Broken throttle shaft
Any throttle body damage
If any of these conditions exist, replace the throttle body assembly.
