car was running sweet until one day it starting to overfuel.. only happens under boost. misses, spluters black smoke but sorts it self out when on boost. happens on light throttle and sometimes on idle. pulled out spark plugs..all 6 fouled.. cleaned em.. same thing.. new 6.. all 6 fouled again.

seems to happen more when car reaches operating temp.

full exhaust

big blitz IC

mines ecu

air pods

ebc

hks ignition system (does n e one know how to properly wire these things in.. i can tell a back yard mechanic put it in due to dodgy solder joins. iv re solder'd it and i doubt its the problem.. car was running sweet with dodgy connections.. then started this issue and i re-solderd thinkin it was the problem but not the case)

its not spark plugs and its not my coils. TPS? IGNITOR? how do i test these items without getting new ones or using known items? ie. certain voltage values?

check for ECU det sensor code.

also check the engine coolant temp sensor resistance is within spec as per the service manual using a multimeter.

if those check out ok then get your O2 sensors checked out.

Might also possibly be fuel pressure regulator. Mine showed simillar symptoms due to the diaphram being stuffed, rich us buggery idle and cruise, and lean as hell on boost, so be careful if it is.
