Spoke to him yesterday It's on the cards, he is flat out at the moment so don't know how far into the future it will be, this is something I'm quite interested in myself
Reminds me of a Mr Carbury talking to someone (who shall remain nameless) over on scabbynet having to ask him to take his name off of something he was selling as his own
To the OP, these kind of things are worth getting right first time, and spending a reasonable amount of money on. It's simply not worth making a £100 saving or more at all..,
The costs involved in getting it wrong don't really bare contemplating, a couple of clicks of bad det with the 2.5 engine will equal ring-land failure and that's heads off pistons out etc at BEST! (the above is the main reason I said in my original reply.. you really shouldn't be accelerating hard until it is mapped after fitting a decat)
Keep us posted how you get on.
PS... My car was road mapped for years.. never saw a dyno until I felt like finding out!
