      Good tune

      Posted by Jon pastor on Oct 10th 2020

      Turnaround was fast, completely changed my car .. it became a total beast and customer service was excellent. Took 30 min to download the tune and 5 minutes to upload. Differences are night and day extra power and tq is truly evident.. glad I went with ess instead of dinan couldn't be happier!

      The easiest 30% horsepower boost ever!

      Posted by Marco v.Katwijk on Mar 3rd 2018

      For me this was a mouth to mouth story. I was so impressed by the potential i bought it. It was quite easy to work out the procedure. All working perfect. More Nm more horsepower.

      Very nice tune for a good price. Runs very smooth on gearshifts after the tune.
