Bought a factory display model 2014 M109, what needs else needs to be done after the stock exhaust is taken off, i.e. servo unit, and retuning to avoid the FI light from coming on/burning out? Any info would be greatly appreciated.
Depends on the exhaust. Some come with its own servo. If not you might need a servo eliminator depending on what year 9 you have. That should be it. Unless you replace the gaskets and bolts. Sometimes the bolts get chewed up taking them out because the stock bolts have loctite on them.
I'm thinking the Freedom Performance curve. They don't mention anything about a servo, thanks for the info!
Before you jump the gun, and assume anything, you should first PM either Big-B or Poseidon, as both of them have that same exhaust, and they will be able to give you all the info you need about that exhaust.
