Hey guys, So I've got the carbon build up code and I can't pass emissions testing (P0491). I don't feel like removing the heads right now so I'm thinking a tune with the SAP delete is the way to go. Are there companies that just offer a SAP Delete option with nothing else? I don't really want to get a full tune flash with every single option right now. I just want a flash that just deletes the SAP. Who offers this?

You may want to contact Evolve, JailBreak or Frank Smith Tuning.

Is this an E39 M5?

It may be the carbon build-up but there's a bunch of other things outside the heads that may be bad and are easy to fix.

Yes its an E39 M5. February 2002 build. That Shark injector seems to be my best bet.
