Sorry guys, just been away and so busy over the last few weeks not had time to complete a proper write-up!
Install was perfect but had an unhappy high pressure fuel pump on one bank which slowed the tuning process, replaced it and started over, all good.
Brought the car home weekend before last but we are still finalising the mapping (touch rich on cold start) so may take a couple more map tweaks before I get it on the dyno for some figures on UK fuel. All testing/logging has been on the road to date which I think is a good thing for sure.
Can tell you now the car drives beautifully, the torque is so low in the rev range its a joy and past 5k you need dry roads or the ESP struggles in 4th !!
Will look to get some pics/vid & Vbox data up over Christmas!
