I think that is a trifle unfair if I may say - I believe Bap had done some 18,000 miles on his S/C before selling it (with no issues). Stephen has done some extensive changes over a typical install - he has the kinetix polished intake (which is notoriously difficult to tune) and he has had it tuned so it is not stock.
Mine has done only 1,500 miles and is standard as far as can be standard
why taking it personally? That is my opinion on used stuff, especially when your engine's life depends on it really
Not implying anything on what you are selling, but I am still entitled to voice my opinion, as you are to plug your item for sale?
