After some let say some quick driving, with antilag on, mainly from first to 3 rd.

Now when im ideling and i blip the throttle i get alot of black smoke out the exhaust and a rattle from the from the engine like something is loose.

Anyone got any ideas what i have broke?

cheers

 

Over fuelling (too much = bad) oh and I hope the "anti lag" was on a private runway as its illegal to use on the road

anti lag eventually brakes ur headers, its really not worth it

 

yup i no sthe stress antilag puts on the headers. dosnt explain the black smoke though.

 

As Tony said more than likely overfuelling. Too much and it can lead to bore wash which will kill your pistons, that rattle should be investigated forthwith as it could be serious.......

 

I had something similar on my old wrx I had forgot to tighten the dump valve fully when I fitted intercooler it let air out and hence car over furled massively so could be a leak somewhere after the maf
