right im getting quite desperate now, even considering selling up!

took the car to msd on monday for full set up and diagnostics as its running flat, should be around 200bhp+ but feels about 20bhp!!

they said the cam had signs of wear and this was my problem. i've just returned from holiday from 2 weeks away, car has been sat on the drive unused in this time. it now runs even worse so dont see how it can be the cam?? its not been used to degrade it anymore than it was.

the car started to run odd after swapping my gearbox to a fiesta rs turbo box about 6 months ago and has got worse and worse ever since, all i can think is i have an air leak somewhere, any ideas on how i can solve this?

cheers!
