Nice job on the intercooler. Get those fog grilles in asap though, looks a bit pikey without them!
Have you got an uprated fuel pump? If not, it's really worth getting one. My standard pump struggled with my Stage 2 R-Tech map, got a few fuel cuts which aren't fun at speed. I was miles off requested pressure. Got a Loba in now and it's much better.
Tweak to 2+ at R-Tech with a proper pump and that cooler will give your midrange a very healthy bump, and you should be into the 280s at peak power.
