i had a 8ight t 1.0 with a rb c6 with a jp-4 pipe on it running trinity 20% 13 clutch bell and 48 spur truck ran great pulled hard and had nice top speed
now i have a 8ight t 2.0 same motor and pipe same gas everything the 2.0 runs 13 clutch bell 50 spur the truck doesent have top end. motors running at 220-240 at the glow plug but the motor doesenthave the rpms it seems like its running rich but if i lean it to 250-260 it has the top speed WTF
