I hope to get an appointment tonight. If not then later this week.
Until then I will not test it to the max.
Btw. I have to add that the downpipe from Ecotune was a perfect fit. All fittings and fitment was spot on. Respect to Ecotune for the product!!! :-)
What took the longest time was to remove the DPF. Quite big and a bit tricky to get it out.
