i did think on painting it black but in the flash it looks mean. Now I have painted the grills black i think it looks really agressive.

IMO black grills are mean mine is black with black grills and looks good.
Im not sure if you should painter cooler black it depends on the look you want 1) sleeper style or 2) move out of the way or my intercoller will eat you!!

I agree re EGT going high. I may end up just doing the CAT but only as a last resort.
I also agree re smoke but only while the turbo is spooling up. Why if the AFR is correct will it smoke. I have seen loads of highly tuned Diesel cars with no smoke. Diesel's only smoke when there is not enough air to burn all the fuel.
As for all the sensors my tuner will do that for me. From what I have read it is pretty easy when you know what you are doing. A few adjustments in the file solves the problem.

I've seen stock 272hp cars with just drilled DPF's (CAT still in place) and it smoke under wot. To eliminate the black smoke to need to play with high amount of boost to burn all the fuel. I don't know how much you can play with OE turbos with a free flow exhaust system, but i doubt that it can go +2.3bar.
I have a friend that had 400hp with just a remap in his 272hp car. It was pretty fast and capable of doing 310km/h (GPS measured), but the DPF wasn't capable to deal with all the unburned fuel because after each top speed run it needed to be cleaned and recicled. It took 2 months for the small turbo failure. The parts that got loose from the small turbo damaged the big turbo and it contaminated with metal particles all the turbo/IC piping system. He had luck because nothing went into the engine causing a major failure, but the turbos, some new parts and the cleaning job cost him 5000?. After that he detuned the car.

Yeah chance you take trying to get as much bhp out of a car as you can.
I have no issue fixing things as and when they break. Reconned turbos are not expensive and because they are not VNT they can be made very strong.
I will see how it goes. I dont think 400bhp from a twin turbo 3.0 diesel is being silly, it may take a bit of time and money to get there with out things breaking but I am 100% sure it can be done.
if the VAG lads can get 400bhp from a 2.0tdi no reason why BMW 3.0d can't

My Ride: Black 535d E60
Black on Black, Shadow line in and out, sun roof, comfort seats, PDCs, navi, Sport suspension, Hifi
The most interesting test would be to dyno and performance test:
1st dyno standard (or standard+big IC)
2nd 1/4-mile with above setup
3rd dyno remap+big IC
4th 1/4-mile with above setup
That would reveal real world gains and performance.
I had my 535d DPF removed and custom remap done in April (no other mods), results are found here https://5series.net/forums/index.php?showto...290&hl=535d
Yesterday i did two 1/4-mile test runs 1st was 13,4@105,3 and 2nd 13,35@106,4
1st dyno standard (or standard+big IC)
2nd 1/4-mile with above setup
3rd dyno remap+big IC

Yeah I have read your results before. They look good. I would have expected more power higher up the rev range due to the free flow exhaust.
My next mod if no Cat or DPF. I agree I should have done what you suggested just never got round to it. My closest rolling road os over 50 miles away and I was being lazy

My friend with 335d (cat+dpf removed) remapped his car with same tuner, but had a few horses less, 60Nm more. He does not have this problem. Mayby due to CAT also removed -> less back pressure->no boost creep.
Beware of the infamous BOOST CREEP
