We are dealers for the Hondata range of products, which are best suited for your car as they retain the OEM ECU.
A K100 supplied, fitted and dyno tuned is £765.00 while the Kpro is £985.00. If you already have one of these, mapping on its own is from £350. The only difference between the K100 and Kpro is a USB port, which accounts for the extra cost; functionality is identical between the two. A Kpro is only required if you intend to map your own car or datalog.
Typical gains, even on a 100% stock car will be 10bhp at peak and 40bhp midrange with improvements in MPG, these will increase dependant on the number of power related modifications to the car.
