When purchased in 2005, astage 1 was addedat dealership for a 2005 Electra Glide. I recently reinstalledthe original stock mufflers. Do Ineed to reverse anything else that was donewhen the stage 1 was installed? Thanks, Bob

 

Did they do the ECM down load with it...if so you will be a bit rich in the AFR, not a great deal but a bit rich.

 

Is it runing rich going to cause a problem. should i go back to dealer?

 

The stage one download is 5% richer over the Base map...I personally don't think it will hurt the bikes performance as much as it's going to lower your gas mileage. The mileage will drop to around 39 to 40 mpg...that is an educated guess. If it bothers you to run a bit richer the dealer can put a stock download in the ECM but be ready for a $150.00 charge.
