You have not met Alex then obviously......
There is no point at all on coming on here posting 1/4 mile times and dyno plots if you just throw up yours hands and say nobody in scotland can fix it.
I'm sure that Alex could check the car over to make sure that there is nothing wrong with it. If it is the case that the car is desperate need of mapping then don't mess about and get down to RS Tuning in Leeds or Abbey ASAP.
It is obviously causing you great distress getting 15 second 1/4 mile times so I would be looking at getting it sorted quick.
+1 - we're all giving you the same advice here
