Mine used to stall when coming to a stop... but it was the greddy type rs dump valve leaking... fecking horrible dump vlave if your running a MAF sensor by the way...

It could be a boost leak (Most likely) or you could have alook at your AAC valve (Top of the inlet manifold...) and give that a good clean out...

if its standard then the 0.55/0.6 bar is ok as thats the standard boost.

No, its NOT standard boost. Standard boost on an S15 Spec R is 0.7 bar. 0.5/6 is standard on a Euro S14.

oh, i thout 0.55-0.6 bar was standard, because mine was about 0.55-0.6 bar before the exhaust mods etc then rose to 0.7ish

Just out of curiosity, at what boost level would I warrant a metal gasket upgrade? Thanks.

Ive changed mine to a 1.8mm Greddy metal one and im running 1.3bar...
If youve got the time and the money its never a bad move to change it anyway... although while your changing it i'd recommend changing to ARP head bolts while its all apart!

After i have the blitz bov installed the rev does drop to 400rpm whenever i put it neutral while stoping the car. But after i installed the oil catch can with a route out method, it did stalled quite often.
Heard that e-manage got a function whereby you can adjust or stabalized the voltage in order to remove the stalling.

i experienced engine stalls sometimes....but the mechanic recommends about getting the new AFC Neo...or n my mind, i probably save some coins and better get the powerful APexi Power FC..what do you think guys?????

Definately PFC! AFC neo is just a piggyback with a flashy screen with no where near tunability than PFC.
