okay, it's a frankenstien motor,... motor is bogging at low RPM, like around 700 to 1000rpm, it seems like it cant breath at normal low rpm....if u rev the motor to like 1500rpm and up it seems okay.... motor is shooting out good compression on all four pistons, it's still around 280psi to 295psi...can't seem to find out whats wrong with it....and oh, if u take it up to like 4000rpm and then floor the gas paddle it seems to bogg too!! and the rpm jumps a lil back and forth at 3500 to 4000rpm if your going 65mph to 70 or 75mph.....weird huh?? any advice lmk..... oh and noww the idel's kinda high too it's around 1200 to 1500rpm!!!!! i think i created a monster hahahahaahah......
