how much would it cost to chip my cav (x20xev)?
what benefits would i get without further modification? ie will performance be enhanced without tb's or cam etc?
The cheapest that I found was £425, this includes fitment and a rolling road session. I was told that it works well with the standard 20xe, I presume similar to yours. The Unichips are matched to the individual cars spec i.e. general engine condition and mods. The unichip is mapped through the rev range, I think at 16 different throttle positions.
Just one point if you do further mods after installation you will need to go back and get the car set up on the rolling road again, which costs anything from £95 - £250 - BARGAIN!
