My RB20’s running well, idles high for a while until fully warmed up like 15 minutes which its always been.
Now when I give it full throttle it pulls awesome but hits a huge limiter/wall at just over 7000RPM which i never had before?? Engines power cuts completely very suddenly, i always let off as thats my first instinct is a blown IC pipe but getting back on the gas the cars fine. Im convinced its not a leak after doing multiple boost leak tests up to 30psi. This happens every time any gear it seems, im fine just driving around but want full potential. For some reason i think its electrical, What else should i be looking into?
TPS, MAFS…bad gas setting off knock sensor…
Fuel pressure is perfect within spec fyi, engine will do this with E cutout open or closed so its not a clogged cat.
