    You can now check your own vehicle gains from the vehicle tuning section above which has been provided by our tuning file writer.


    Our gains that we offer are 100% suitable for your vehicle and is why our gains  are a lot different from most companys. Unlike most vehicle tuning company's that offer you huge gains from a stage 1 remap by putting the boost pressure through the roof and cause nothing but problems down the line, we aim for impressive results that will not cause any extra strain on the engine / turbo.

    Many mobile remapping companies are using jump leads to program your ECU in which is not a safe way to do so, This can fry YOUR ecu and the vehicle connected the other end, even a little drop in battery voltage will corrupt the file being read in which means when it comes to altering and re-writing the file it would have been corrupted to begin with and will NOT be written properly. Maintaining a stable voltage on the battery while programming is a MUST!!! Using a state of the art battery stabiliser you will not have this issue with us.

    Please do your research before opting to go with the cheapest quote or the highest gains. Also like to add that we have GENUINE equipment unlike most that are using the clone equipment which will ruin your car. Make sure the machine being used has the alientech logo if they are using KESS or KTAG.

    Bricked ECU from a poor file / tuner??? No problem we are here to help and fix any problems that you may have been left with :) 

     While also providing a speedy service in which we should receive your file back within 20 mins, 

    There is not a ECU out there that we can not programme as we are using 4 of the best tools available on the market - AUTOTUNER - FLEX - KESS V2 & KTAGG

    We do not use generic map's all our map's are sent to our tuner for a custom written file while you wait. With plenty of add-ons please see service page above to see what we offer.

    Please note that if you have a mechanical issue with your vehicle please do not think that a ECU Remap will fix the problem, we will perform diagnostics before work is carried out to make sure theres no faults. Also if you have a milage blocker / can-bus filter fitted please make us aware as this will corrupt the reading and may lead to your ECU needing to be programmed.
