Hi all, I've just had a 3" exhaust with hiflow cat fitted and an ECU remap done at Manta on my 2.5 MN. It was a low level remap more for towing, not sports driving.
I'm now blowing a heap of black smoke under acceleration to the point of expecting a yellow sticker.
They lowered the fuel at least once but still blowing heaps.
Air filter looks fine, cleaned the mass air sensor and have just added the first dose of Moreys diesel smoke killer. Recently had a new turbo fitted through Midland Mitsi.
Hoping others have solved a similar issue or have some ideas.
