Does this sound a bit high to anyone? I'm only going stage one, not going to be going for huge power. Was already quite unimpressed by them when my renewal was £50 higher than I paid last year, then sky quoted me £600 but rather than swapping I was stupid enough to take a price match from AF. Should have left on principle I guess. Never remapped a car before so not too sure on how much extra it should cost on insurance but can't help feeling a 20% price hike when I'm already a quarter of the way from the year seems a bit steep.
