Can or has anybody tuned out the secondary air injection system of an e39 M5?
I'd rather not pull the heads just to clean the ports.

Thanks As Always,

Sorry, replying by cell phone was a bad idea.
Codes I would like to remove are:
170 (AA) P0411 Secondary-air quantity too low
232 (E8) P0441 Function check, tank ventilation system

The software in the vehicle is Dinan performance so if it can be edited as apposed to a stock eprom edit, that would be great. As always any help is much appreciated!

I've also read that you can flash with euro m5 software to eliminate secondary air injection. Anybody have any insight into this?
