Kleemann tune on new 5.5 bi-t...690HP
BHP? cmon man....




Thats just plain incredible.
Someone ought to TT a 55 think we should see closer to those numbers then. S/C parasytic losses are too much for top end power. Think that should be next phase of mods for die hard 55ers ... for others well choice seems obvious.
700+ HP should be a breeze with bigger I/C or Turbo plumbing refinement , or intake upgrades....
