Well just a quick update and thank you to Unicorn Motorsport.
I had some DFP issues see here
So took the plunge and had the DPF gutted, EGR blanked, & had it remapped. I've had it done for a week now.
It took around 4 hours total.
So what do I think well it's like a different car, it feels lighter, better response, feels smoother, and has a nice little tinny whistle from the exhaust. MPG better? Still too early to tell but it seems better.
I need to put it on a rolling road to see what the power and torque is now but it definitely feels more, and has a new lease of life at 125,000 miles.
If you're thinking about it just do it.
