Interesting stuff!
I think I will get a stage 1 remap from rtech as they seem good value compared to other brands like Revo and seem to still have a good reputation.
Then at a later stage, when it gets a bit warmer I might get out there with a hammer and chisel and get rid of the pre-cat.
I'm also thinking of getting some lowering springs to drop the car slightly however I don't really compromise ride comfort too much, any ideas on how much I will have to spend and any recommended springs? Ive heard h&r don't ruin the comfort, however that was written by themselves so I'm not sure how true it is!
