Let us know how that install goes. Top Speed says you can use an adapter that moves the O2 sensor ½" - 1" out of the normal bung hole….question is, will that throw a CEL? Someone who has been successful please feel free to chime in.
Waiting to get my headers put on BUT WANT TO KNOW WHAT I AM GETTING INTO. How hard is it to re-program with a flashy thing? Where?
