Well the new injectors are installed. and im just having trouble dialing them in at part throttle. at full throttle they work flawlessly but at part throttle anything under 3k it kinda getting a lean hickup /runs rough n kinda lean like up to 15.7 afr on close loop but when i give it more gas it goes away.kinda like if the injectors need to inject more fuel at part throttle. im running fic 750's. when i had my 550's i didnt have this problem
