all done and well pleased, feels like the JK had asthma and I've given it a puffer....now feels just so much better, remapped to how I wanted, you can choose. I wanted everything below 60 to be better. Just feels nippier, quicker and much more responsive. Cannot update on MPG till I've driven it a few weeks with all sorts of driving.Well happy with results.Cost is £299.00 and you won't meet a better bloke to help you, his name is Iggy, he's the MD at Zensport http://www.ruderacing.co.uk/
