Your tuner should be able to tune that stuff out. With these mods I would recommend a dyno tune. Its worth your time and money, trust me. They will straighten out your AFR so your not running too rich or too lean.

Go right back to the shop who tuned your car. If all you did was a dp and tune you should be ok. A friend of mine has an x6 dp, eisenmann muffler and ESS tune since he bought it new and it now has 35k and no problems at all! Its a BEAST
