Don't do more boost, you need a flash, or at least something like an S-AFC, all of us that don't have those need one...

 

All you have to do is have the car flashed or buy an SAFC and have a tuner lean it out for you a bit. You are running rich, thats all.

Thanks guys.

So its ok to have a cloud of black smoke come out when i step on it?

I plan to get it flashed the summer.

 

If you are lucky enough to just have a cloud, it's almost definitly okay... Catless I have a constant stream, even when I'm not flooring it.. well, not all the time, but quite often... and then there's the great popping noise every time I let off, that is really loud, but impossible to hear in the car... You're just fine, no worries
