i have two rs turbo chips....one has a power enginering skicker on it i opended up and found a blue s marked on the chip...done some research and found it could be a superchip. Now the other one i opened up and removed a metal tag...i had been told it was chipped as wel not so sure tho. it has got a small white sticker on it and i think it reads rst 88 s2 AB 16/7/02 i think....done a bit more research and found there could be two types of chip... boost removal one and a (AB) custom one ??? if it is chipped is it ok to use as i am unsure of boost level and ign map ect.... any advise would be great. tried to upload pics but cant figure out how to...if it helps i wil try to upload some. regards ryan
