k with the apr chip its stupid, i use to be all for the apr but im all about revo now, any common mechanic at vw will prolly know about the cruise control stock and just try it to see if your car has been chipped with the revo software and the sps it reflashes the software back to normal or a 93 or 100 octane setting or heck you can even do your own boost and timing
And no you will not be able to over boost the ecu will monitor and at the first site of det or ping it will back down timing or boost so all you do is turn back the knob alittle bit. and the only way they can find out if you have the revo software is if you leave it in 93 octane mode or you leave the diagnostic plug in otherwise they have no way of knowing that it is installed on the car
this for me is a bonus plus with you being able to control the timing and boos tfor yourself makes it a tuners dream come true..
