Terraclean any good?

I had it done last year to my 2.0 TDI, performance was a bit crisper, I noticed it more in mpg, easily got 20 miles more per tank..
 
I've had it done on a few cars now and it makes a noticeable difference. Definitely worth doing before a remap.
 
I would recommend it also. Had it done on my 3.0 tdi, cost £118 from a man called andy clurgy in Liverpool.
very knowledgable fella and professional. I noticed a big difference in mpg and power delivery after having this done.
 
when you say power delivery, do you mean smoother etc? i notice with my 2.7td, unmapped as yet that first is crap. get to 2nd and were off lol.
think before map it needs a clean out done 128,000 miles so its got to be ****** inside.
 
Yes mine is a bit sluggish in 1st also.
The Terraclean helped with that but the most noticeable difference was the increase in mpg smoother acceleration and seemed much more responsive
