Hello all,
My friend has just bought a A4 with a AVJ and is disappointed with the performance.
I cant search the forums for AVJ as its only 3 letters and it wont return any results!!

Can anyone assist in making this old car go better??
We want to remove the catalytic converter, but im sure this will upset the rear o2 sensor and log a catalyst efficiency fault code....???
Is it simply a flash file? Please advise, im not new to electronic repairs, but i am new to modifying the flash data.

Thanks all!!
