i need your help, i cant get my rx7 to redline. i blew my old motor witch did the same thing so i replaced it with a jdm motor and it still wont go to redline and it loses pull at about 5500 rpm also. any ideas??????

 

probabaly from your 950 secondarys.... those are too big to tune in with a s-afc. even at -50% the max correction, you still have more fuel then stock.

 

douple post...
