just wondering if anyone with a front facing intake (greddy, stock rb26, nismo "jun", freddy, hypertune ) has flow benched their intake and determined the leanest cyc, i have a custom intake, and obviously it will flow differant from the others since mine is differant but i want to find a ball park of the leanest cyc and assume that is my leanest as well, also i have ss rb26 manifolds for my twins, and i want to tap the exhaust manfold on that port so my egt reading is super accurate, i was thinking of just using a thermometer on each runner and go from there, any input where have people placed their egt gauges probes ?

Cyl 5/6 are the ones that get the most air rammed into them. My probe is at runner 6.
