Do you smoke?
I've recently had the pressure modification and Autodelta box fitted to my 2.4 JTDm by Mangoletsi, car feels great with much more 'usable' power available but I did notice that it was very smoky, and not just on full boost.
Before going to any extreme lengths I thought I'd try some injector cleaner/fuel system cleaner - Wynns always seem to get a good review on here so I opted for the best thing they do in Halfords - Wynns complete fuel system cleaner. It's been going the through the fuel system via a full tank of BP ultimate diesel (I always fill up with this) for near 100 miles and I think it's getting better already - noticeably less smoke under hard throttle and no visible smoke under normal driving.
So, the point of this post is to ask if any other 2.4 'modded' diesel owners experience more smoke after having the modifications, and what have you done to remedy - if anything?
