I was with Oily on Thursday/Friday for a K04 upgrade (new cams, DTH TBs and ECU) to upgrade my Xpower 140. I must say that I have 100% confidence in his work and it's well worth wait to have a job done to the best possible standard. As you can tell, I'm well please with the end result - a big smile on my face for the 100 mile drive back in the driving rain!
I think we are well served by DVA, Powerspeed, Emerald etc.
Thanks also to Steve Grubb (Grubbster) for sharing his experiences of the same upgrade path and getting me off the fence!
