High boost, low rpm

[ZamS]

Dear All,
Currently, i'm driving 1.8 Mivec Turbo. Sometimes, i experience this phenomena: High boost +/-0.6 @ 2k rpm. Car feels hardly to pick-up. Most of the time when gear dropping from 4th to 3rd. When I release the throtle, and kick back, then the pick-up comes. Is this called "turbo lag"?. Now i'm using GSR injector, TD04, evo3 fuel pump. Fuel management, SFACII. Idling & cruising are very good & satisfied. This phenomena not all the time & only kadang-kadang. Good people in this matter please advise me!!

Regards,
ZAM

could be ur turbine has a problem ,
bov jam ,
actuator rusted
internal wastegate hole got cracks
or simple.... TUNING

your low throttle settings at your SAFC......try check n retune

 

[beyond_4896]

yes, ur low throttle setting.

normally for bot , use management which got boost sensor build in better!
mt4 or e-manage.

maybe too rich before boost

think so

 

[flushafteruse]

check your timing marking too...too retard maybe

u should check ur feul by using air fuel ratio ... maybe the feul is too rich or too lean.. tuning air fuel ratio is the solution
