4agze Sc14 Full Throttle Problem

[miriguy]

hi guys

i have installed SC14 in my 4AGZE MAP engine. No problem with 1st and 2nd gear while full throttle. 3rd or 4th gear, when full throttle, car jerks, supercharger light goes on and off. 50% to 80% throttle, i dont get this problem. No jerking problem when i slowly rev to high speed. is it got to do with belting? i have tighten it also, maybe not tight enough? Problem with cooling system?

my setup;

4AGZE Map from Trueno AE101

Oversized pulley (boosting 1 bar with SC12)

Stock ECU (took out emanage)

SC14 from 1G with smaller pulley

Stock Injectors

Stock Intercooler

Evo Fuel pump

Sard (not-so-original) adjustable fuel regulator

thanks for reading
