just checked my bag of nozzles and i have both my M15 and M2 nozzle. looks like im using the M5 right now 0_o
edit-i remember b4 i got the devils own controller, i was using a boost activated switch and the M15 nozzle with washer fluid. i was able to run like 25* of timing on a 3.4 and at least 19* with the 3.2" maxxing my stock injectors. however i was running out of washer fluid alot when i was spraying and since the boost activated was just at one setting, it wasnt spraying linearly with throttle nor the map sensor.
