    About Our Happy
    Customers Feedback

    I had A stage 1 remap today from GW Performance. Converting my 227BHP TO 301BHP. What an improvement. They also sorted problems on the car that BMW (Carlisle) could not find. I was very impressed and couldn't of been happier. Highly recommended with a great deal of experience and knowledge, Thanks once again, will be sure to recommend you in the future

    Had a stage 2 remap, took my 2.2 up to 204bhp. Obviously the car performs much better than before but I wasnt ready for just how much better the engine ran under normal conditions, idle is smoother response is more fluid it feels like a new car to be honest. George, who does the remaps couldn't have been more helpful. Smiles per pound there is nothing to beat a remap.
