Hi all,

I've not long got my astra coupe turbo and after reading the how to's on here i thought a nice easy mod to start with would be de-restricting the air box! I followed the guide and after putting everything back together and starting the engine i noticed that my exhaust was very smokey and smelt alot different to normal!

I've now put all the original pipework back into the airbox and it seems to have cured the problem! I did notice that when i took the bottom pipe out of the airbox it left an extra hole where the clip used to be, could this be the problem? Not sure that it wold be though as it would just be feeding more air into the airbox ?

Any ideas would be greatfully received.
