black marks? because you're running rich i presume... get the running rich problem fixed so it doesn't make black marks anymore
as for the remarks about the pit inspectors and how they're not stupid... we all know they check at least ten cars a day EACH if they're at a busy Vehicle Inspection Centre... thing is, they test the car as it is... not how it COULD be or how it WAS.. just like how a police officer will give you a yellow for what you HAVE on your car... not what they THOUGHT or KNOW you HAD
paying $480 for the first time is cheaper than paying the $1200 for KEC and to legalise your modifications
the second time you're paying another $480 so that's $960 which is still cheaper than $1200
and the third time would be $1440 which is only $240 more than going to KEC...
and if you really want to legalise your car without going to KEC... just buy permits so when you do get a yellow (even after the police officers ignore the permits and give you a yellow anyway) you can breeze through the pits and won't ever need to do an IM240 test
thing is, how many people will be pinged 3 times to get the yellows? HARDLY anyone here would have had that many yellows and i say hardly as i know a few people here who have had a few yellows before...
thing is, the $1200 i quoted is the CHEAPEST the testing will be... if you're unlucky you'll have to pay more
to get the yellow and have to take the IM240 test... you'll have to first be pulled over, then get yellowed, then not pass the pits, then get told by a pit inspector you're required to take an IM240 test
if it happened to you you're bloody unlucky, all i know is that the odds of you getting done for an IM240 test compared to just getting the yellow off by removing parts or not getting the yellow at all are extremely slim
lastly... all the workshops i've spoken to say that most pit inspectors don't like handing out the test, especially those at Midland and the chief inspector there hates the idea... and they really only target (very vague statement i know) cars with high-mounts and mods at that level... if you've got an aftermarket intercooler and cat-back... the odds of getting done are slim
as mentioned, nothing personal... but if you've been over the pits lately you'll know what i'm talking about... if you haven't then you won't know and will continue to disagree
