Yeah I think you are right Neil I was just very bored yesterday and to pass the time was reading all sorts and the Tom's tec and Mines vx-rom were all bits I had never heard of before. I was looking at the e-manage ultimate at whifbitzs for £550 ish minus harness but would rather get the manifold and rest of exhaust finished first, new o2's, service ect but find it a way of passing a few hours while dreaming of small gains.
On the plus side I doubt any of the Ecu upgrades will ever happen due to poss going Na-t in the future, but then again when I sort out the other bits I may decide adding the emu would cap it off and be a good finish point for the NA seeing as I would of changed the whole exhaust manifold ect and not be bothered about going NA-T and having to swap everything again.
