Gareth,
as you rightly assume, many people have chosen tuning paths that deviate from the
JCW. A search on the engine and performance thread will reveal many musings as to which tuning package is better..................but ultimately it all comes down to personal preference and budget.
I run a GTT tuned car and am very happy, friends of mine run
JCW cars are also happy whilst others run Lohen/BBR/Hartge/AMD etc and are also happy.
So you pays your money and you takes your choice - personally I'd go GTT every time for value, quality and service.
