it's from a company called RGS motorsport in Northampton, on a dynomet.
they don't do many fords any more, more into jap stuff. they have a gorgeous skyline they are building up , expected to be circa 800bhp

i popped into see them a few weeks back and found them to be really good, friendly and helpful. very knowledgable too. i had asked them to tune my engine and when it couldn't be done because of an air leak ( after they had looked at it for a while) thay did it the following day and charged me nothing pretty good when your paying for peoples time and knowledge that they be so accomodating. would recommend them to anyone

they also built my engine so if the figures are good then
