Hi Stu..
Tks for the links..a few questions more specific to my car (large turbo escort cos)
1- How much to fit closed loop fueling fitted and setup/mapped...
2- What about closed boost control..is it easier to use a greedy type boost controller / or air injectors (if they are closed loop)
After reading all the posts my head is spinning but it seems the way to go...that way u know the fuel and boost you have got...seems crazy to just put the fuel in and hope the boost is ok..although i though the map sensor controlled fueling

now I am confused....anylight would be very welcome...
I suppose what i am asking is what is the best boost/fueling setup i can have for my car and how much is it going to cost me......
Thks Malc
