Best remote ECU remapping tool and map

Hi. next summer, i would like to make some upgrades such as akra exhaust. Than i would like to have my car mapped with new ECU, which will fits with this upgrades (ITG panel filet, akra exhaust) but i live in Slovakia so theres no way to get it mapped on some dyno or something. So only way is to buy some remote ECU tool. Which is the best and also which performance center got best maps? K-Tec, Fastchips, Bluefin superchips or RS Tuning ?
