I did the cleaning myself. I'm based in Yeovil, Somerset. I did the cleaning at MRC Tuning (good friends with owner), so that I could see the gains (if any) and also to get its stg3 map.
The inlet cam was used as the fuel pump lobe has higher lift. Was hoping to not do a hpfp kit, but as I'm pushing the car as far as I can, it was done (pump kit) for safety. The cam was 5-6 hours with doing belt at same time and the cam is about £265+vat! But it gave me the chance to check cam pulleys and chain etc.
Will post results later next week once it's all finished and dyno tested
