I fitted a bailey DV to my focus , it worked beautifully for 3 weeeks then started with the dreaded stalling problem.
After a quick conversation with james at pumaspeed he advised me of this adjustable turbosmart dump valve.
A long drive from newcastle was rewarded within a few minuites (thats all it took) no stalling.
thanks james its still going strong after 3 months
