I am presently mid re map of my RCZ THP Sport - owned it almost a year now and following installation of a cold air intake, upgraded turbo dump valve and solid alloy turbo hoses I am pleased to say that we have mapped to 196 BHP from the stock 156 BHP.
As part of that process I had my inlet ports checked and walnut blasted - yep they opened the ports and blasted them at high pressure to remove all the gunk that builds up on the valves pre direct fuel injection.
I am sure that some of you will have experience of this and I would be interested to hear how you got on with it. My experience so far has been a smoother more responsive throttle, much better torque across the lower rev range with the main power coming at at about 3900 revs and it allowed me to map to stage 1 up to 196 BHP.
Before and after photos below (I know they could have given me any old photos but I have to trust them that it is my car ).
Anyone interested in the mods I have made just let me know and I will post pictures:

- GFB dump valve upgrade
- Cold air intake to replace the stock air filter system and box
- Hard alloy intake pipes
- Stage 1 mapping
- Walnut blast
