what is your boost u running? your rev cut will come in only at 6.8k rpm..is the car jerk during 5k rpm ?? there are possible due to boost cut not rev cut..if u running at low boost than will likely your spark problem..may due to spark plug, cable and distributor..check this few things first..

i took out my tulang ikan n now suppose to run on standard boost 0.6-0.7 but the boost will increase around 0.9 at 5k rpm then got buzzer sound 'tut' then even i step full pedal also then car wont go....must change next gear n the prob happens at every gear 5k rpm....

ur boost maintain on 0.9 bar?? did you do any adjustment on ur air flow? what plug u use? when last change? what turbo u use? urs stock 180?

- check ur plug, check ur plug cable..

your boost only 0.9bar. i will say 99% not actuator problem.

where you located? if you are in PJ area i can help you to check on your problem. normall is either (bov leak, spark plug, plug cable, IC leaking)

im in nilai...studying...
but usually weekends i'll go subang...
i check my IC hoses all sud be ok...if any part of IC or IC itself leak then i cant achieve boost rite??...
i'll check my bov tmr....
u mean plug cable is either 1 of the cable spoil or wat...??

check your plugs... like tkk said, check your hoses...

change your spark plug, I'm not sure u r using the right plug... the important plug for different caris that the tip's gap is different..when this gap runout due to wear and tear on the tips, or dented.. u will experience misfiirng, this is why u have the feeling of cut... just make sure uc hange the plug is for B8.. irrespective of what no ..6, 7, or 8 etc.. this is basically is the heat rating..if u r regular to subang join our TT ..ussually will be on friday..

 

[9188]

phreak, 10s for ur info....i'll check all the hoses...
laserman...10s too....

oh too bad.. the pettt sound seems to be air leakeage.. check the hose after airflow to trottle body.. check any cracks or loose hoses.. when u change the plug what colour u see on the plug? u may different combination of problem here.. is hard to tell you all things here unless have have seen ur car..anyway

try to call tkk pomen, he can help you out on this problem..he have years of experience with B8 ..no worry bro.. good luck..
