hey guys heres my problem, wheni i bought my 87 T2 w/ jspec S5 T2 swap it had full 3' exhuast. couldnt go past 4000RPM because of fuel cut off. so i bought a used racing beat one and everything was fine. about a week before i but my 255lph walbro pump in , it starts cutting off at early 6000's but only when its warm? could it just be the fuel cut defensor or maybe injectors too small? any ideas?

 

too small? they are acting more like larger injectors since they are flowing more with the increase in fuel pressure, you need to tune the fuel with an AFC or standalone.

 

ok i was gonna buy my buddies Apexi SAFC... i guess il try that
