ok i didnt diy my conversion as when i had it done 2 1/2 + years ago there was no off the shelf chips for greys.

that said i know how stu operates and if it was difficult he wouldnt let it be done diy to protect customers.

what i will say is, its the best conversion you can do on a cosworth. L8 closed loop drives superb on or off boost and is very good on fuel whilst running in the closed loop parameters.

Do it !!! you will be very impressed.
