I live in Horbury, TRL I went to once..... Never again. And if you want to stay up here, yes, go use RS tuning in Leeds! They did mine twice, it never blew up or anything, it spat flames and made 422 bhp at 1.5 bar on a GTX3071R. He doesn't push the car to its limit but puts on a pretty good safe map that makes alright power usually!
If you mention that he did mine to Paul (that's the owner/mapper of RS) and mines the only blue pulsar he's done, and that I suggested you go there, I'm sure he'll be happy to help!!
Other than that it's a long trip down south really!
