I was watching an Option video the other day and one of the tuners at JUN Auto was tuning an sr20det in an s14. Unfortunately, neither my friends nor I speak Japanese so I didnt know what they were saying when they did this. The tuner had the car on a dyno, did a pull, and looked somewhat concerned after the pull. He removed the IACV and drilled out the bypass hole a little bit. What would this achieve? Would this help alleviate some of the problems of running rich when the BOV vents to air or help with stalling on deceleration?
