Same tank of fuel used.

Mods are DO88 intercooler, MST turbo inlet V2, forge charge pipe, turbosmart plumback, Milltek sports cat, Tesco Momentum

The throttle response is amazing, the car makes some different sounds internally at times altogether its throatier and more raw sounding in all drive modes. Even comfort now sounds psuedo-exotic.

Hope to get a chance to ring her out on B roads this weekend coming. Not especially sure I need to mess things now with BM3, tho I had wanted to code cold start out.

Pre-intercooler being upgraded three runs were done in quick back to back succession, in fact the third run made the most power. So much for my heatsoak theory, on the dyno at least it didn't display this behaviour.

I have convinced myself I can feel it on the road in some circumstances however.

Car feels like a big N/A lump now it's lovely.
Can you clarify the mods before and after, please?
