If you've got nothing left then it won't hurt to:

1) Check the throttle position sensor (Potentiometer top-right in your picture with 3-wires plug) for correct opperation in real-time data mode. This should go from around 1% to 99% (Or 0 degrees to around 80 degrees angle of throttle pane), smoothly and properly as you press the accelerator pedal. Engine can be off for this.

2) Absolutely check the valve tappets gaps which should be 0.20mm intake and 0.40mm exhaust. This makes sense because when replacing air-filter and changing exhaust you've suddenly changed the 'breathing' of the engine which is quite closesly tied with this adjustment.

'Just my 2 cents and hope you sort it. Wink
