I can recommend Rick for a remap on these or indeed any car, The fact is he is extremely knowledgeable and experienced and he does the mapping himself. They are not bought in maps from some other tuner so he can make adjustments on the fly to get what you want.
As he says the mechanical side of the work is also done very well.
If you are getting fumes in a car then there is a leak somewhere in the exhaust system, possibly the DPF wasn't welded back up correctly.
Here is the DPF On my car after it was welded up, you cannot see any of this as it's up against the bulkhead, To anybody looking at it they can not see any welds unless it is removed.As you can see the quality of the welding is also very good.
Having the DPF / Cat removed and the EGR deleted is the best thing to do on a diesel, As the car no longer regenerates you save fuel , the back pressure caused by the DPF is many more times than that of the exhaust system. If you want the best noise / performance/ fuel economy out of the car the DPF has to go.
To get the best performance out of these I would say the standard intercooler is possibly too small so needs replacing, you don't need to spend £800 on a Milltek exhaust either, just removing the baffles in the rear box or having custom exhaust rear boxes will get you a nice noise.
The numbers on the dyno look good but I think the performance on the quarter mile is more telling, 13.36s at 103 mph .
Have a look around on the net and see what kind of cars run this kind of time.
And my car is an estate, I did remove the back seats, a 15 minute job that saves about 40Kg, but otherwise it was standard not a stripped out 1/4 mile special.
