Subaru's hv an in-built Shift Indicator. D Small button on d left of d Speedometer. As for maximum power is at 4,000 plus2 to 6k RPM. After dat d powerband simply drops. I set up d shift indicator to be at 5.5k RPM. Juz shift up when reach 6k. More than dat is redundant n will be detrimental to long term Engine Health. I'm using stock IHI VF42 Twin Scroll Turbo n boosting at max of 1.3 bar. As for Increasing the boost it is highly recommended dat u hv a proper Engine Management System to go along with it. High Boost=More Air. Therefore, AFR (AirFuel Ratio) is affected. Proper tune will get d desired AFR thus maximizing the power gain from Increased Boost n also preserve d Engine. There are many places where u can Reflash ur Stock ECU. Good ones are AE (Auto Enguinity, Ah Chai), RS Motorsport (Micheal), LMY Snailz Garage or better known as LMY (Andy), GT Auto Sunway..All are highly experienced in dealing n tuning wit Subaru Engines.

--yes,stock already got shift light indicated,im set as 7k rpm

2.how much stock turbo & engine max boost in safety ..
*currently boost up to
9.8-1.0 bar when 1st -2nd gear , 1.1 bar-1.2 bar when 3rd - 6th gear...
**best is to set it @ max 1bar.
--is too hard to adjust fine maintaining boost(1.0) as will goes up when 3rd gear above cause im using manual boost controler..

3. im face turbo lag ,any advise to advoid??
** i tot you're using ball bearing turbines....shouldnt have much lag.
--im suspect the cai aps 70 was effect to turbo lag,that why im use to reflash the ecu..

4.any recommend to flash the stock ecu??and how much the budget??
**not sure bro....try asking those tuner workshops in sunway.
--is ok bro... im thanksfull for ur opinion...

since u r running 70mm aps cai, this etup required you to flash/piggyback ur ecu in order to reduce turbo lag since afr is affected.

if 65mm then its PnP
agree,.... that y im need all seafu to recommend me a better tuner and place...
im prefer to reflash ecu...
