over the last week or so mostly in 2nd and sometimes 3rd the car seems to boost cut......and fires a few loud cracks out the of back sometimes, i noticed on the commander a peak boost of 1.39 bar tonight, yesterday was 1.42!...max setting on hi boost is 1.3 bar, is this boost creep/spiking im getting?..also noticed a max Injector duty cycle tonight of 97%

its a MY99 uk turbo with VF35, STI 8 TMIC, Walbro, Sard FPR, 440's and apexi power FC mapped by AFP

cheers lads for any help in advance

the boost cut is 0.2bar above the boost target so I assume it is not currently on the 1.3bar setting?

check the pipe to the acutator is secure, if it leaks then it will overboost.

I presume it was fine and just started out of the blue or has some work been done on the car?

Thanks for the reply JGM

yeah it has only started over the last week or so approx, i hadnt been able to drive the car much as i had to SORN it due to delays getting an MOT date...

Could bad fuel be causing it? i had the above mods fitted on the same day and then the car mapped on what i know is good quality super(just before i had to sorn the car)and it seems to be acting up a bit since ive goot it back on the road but have been using a different petrol station(texaco)close to home(the good fuel is a 50 mile round trip)

didnt notice any pipes disconnected or anything but i will have to check when i get home
