Injector duty cycle does get real high in the performance style mode so an larger injector upgrade will be somewhere in the future.

GBIts unreliable Ive had the kit omnmy car for about 6 months, over time it has started giving me issues that make ne uneasy about driving my car, sometimes the engine when i start it, its surges my afr gauge tells me its running lean. Its fixes itself after i restart the car. The worst is sometimes the car will randomly run super rich and stall out. Everytime this has happened there is always an issue with on the app. It says the ethanol sensor is not connected, or injector capacity insufficient, my injectors run at 35% IDC at WOT. Seems very unreliable i cant drive my car too far for fear of getting stranded.
