this depends on the overall package because the combo of cams, turbo, intake and IC piping will sometimes produce some weird pulses in the intake that will mess up the MAF.
For the record, I installed S2 on evo 9 with hks turbo and my own IC piping and IC + ETS steel intake and on MAF it was impossible to get to idle and on small loads it was real bad... fueling was all over the place... even with getting mivec to do -0.6 deg intake cam timing
We then replaced the ETS intake with stock, and then it was quite ok apart from idle itself which was ok when tuned for 1100 RPM and a bit richer AFR but it always had this idle drop from time to time... sometimes almost shutting off..
When we switched the car to SD idle is perfect.. 950 RPM and 14.7 AFR.. and works fine even with a couple of deg of intake cam advance on idle and ETS intake.. ..
