I'm interested in this for my JCW, how easy is it to install? Given that I am technologically and mechanically retarded?
I won't say a chimp can do it:laugh:but it is very easy on the Mini access wise. About 15 mins to do with 3 connections-1 to MAP Sensor,1 to Airflow Sensor and the last to the Boost P/Sensor (the only dismantling is to take off the air inlet duct....2x10mm nuts...to access this one)
I don't know your preferences but I like the box due to the fact it can be removed easily (remember warranty position if using an ECU tune) and it can be sold on as well,which I have done easily before. I have had no problems with 3 previous boxes ie no engine management lights etc.
As far as dyno figures go I'm not too bothered as I prefer to FEEL the difference given that some of the claims are maybe optimistic!! With everyone its a case of the more the merrier

not that I personally drive like a lunatic, I just like a bit of fun now and again.
Of course you should get some figures if choosing an ECU tune which should help your decision.....I'm surprised there is not more info from MCS owners by now.....maybe not on the forum tho.
The last dyno figures I had were back in the early 90s when my Fiesta RS was chipped at Power+ Engineering in H/Wycombe. It was +36bhp/42lbsft and that cost about £400 then!
