Got a reply from Steve at Statllers.
So the Revo upgrade from stage 2> stage 2+ is £60
- £60 to load said map ^^
- £60 for a few runs on the dyno to tweak and find my B T F settings
- £350 to supply and fit Autotech internals (or £400 for me to find and fit a 2nd Loba pump)
So £530 (statllers) to £580 (loba) for me to go to stage 2+
Probs go from my 330bhp>350-365ish & 330ftlb> 360-370ftlb peak with a load more mid range under the graph....
