GEEZ! Work has been kicking my assssss! Meant to check back a while ago.

That’s good to know, seen a few going reasonable and thinking bout repowerimg this winter for a little better fuel economy than my pm is giving.. I know the 300 isnt gonna be any better?? Just a thought for big numbers I had.. was more curious who’s done it and there opinions and results.

If you want fuel economy roll with 250xs. Loads of torque. Will likely push you xb2003 as fast as you care to go. If you are okay in the low 90s run 1.75 and be quicker, if your more into topend run 1.62s
