Bravo x vs bravo xr
 

Does anybody know how much speed loss going from bravo x to bravo xr on a silencer

you wont notice any difference going from a standard bravo to an XR

That nice to hear was hearing that I could lose up to 3 miles an hour just wasn't sure how that was happening with same gear ratio either way going to find out soon enough

Depending on the overall setup of the drive, gear ratio will vary it, and an option ITS Box will vary it as well, with a 555 CID in it, probably nothing you're going to notice.
