depending who maps it the rate would be around 550gbp which=638 approx for unlicenced ecutek and 300gbp with licence=348 so when you add up say 250 +348 it nearly 600 so i would just get your own ecu mapped less hassle and less effort rates above based on jgm rates.unless your mates does you a real good deal on the ecu id just stick with your own and get that mapped
