Default black smoke

Hello! recently i have noticed that on wot it comes black smoke......

Doesn't black smoke usually mean the car is running rich?

I thought black smoke was detonation, at least if it comes out in puffs.

black smoke is unburnt gas...not detonation. dentonation is where the air/fuel; explodes to early, but it doesn't cause black smoke.

First you should get rid of that MAF translator and then take off those MAF ends and put some stock ones back on it. I've never heard anything good about messing with the MAF. Also, it might be kind of hard to do in Sweden but you should get a dyno tune so they can get the a/f ratio where its supposed to be(12.8-13:1).

if the car isn't running bad..I wouldn't worry about it, but if you cang et a dyno tune..i'd get it because your leaving some power on the table running so rich.

Do a search on maf ends and you will find that they are nothing but trouble. Id take them off. Id ditch the maf translater and wait for funds for more serious mods. Before you spend more money id study up for awhile here, then go for it.
