May have to pm statler steve before the show, see what can be done, was offered 10% last time i was in.Yes R-Tech may be cheaper, as many people post, but for me it also comes down to distance for tweeks or any issues, r-tech are miles away.
I had mine done at Inters 2010. They used B6T6F9 for settings. I later switched it to B7T5F9. All without logging. I later had it logged and it was pulling fine with no issues etc.IIRC the yellow lights were on cars with Stage 2/Stage 2+ remaps.
