So Bash has just put a hdi gearbox in my phase 1 and now when I'm at 70mph it's running at about 2200rmp, is this about right...? I'm wondering if my speedo is out now as at 70 it feels too slow and when I'm at 80 I'm at 2500rpm (which I've been told is more like what they run at with a hdi box at 70...) any advice would be great! Thanks [emoji4]
