ESS Tuning

From wild animal to MONSTER!

My dad has owned a 535d for 3 years now, and has been thinking of getting a new car for a few months now. But I tipped him about chiptuning, and this caught his interest, eventhough we were both a bit skeptical, we read on different forums, and concluded esstuning.com was the right one for him.
My dad has emigrated from Norway to Spain, so I were to order from Norway and bring it down to him on my vacation.
From order to delivery it only took 3 business days, very good.
When in Spain we were eager to get started, so we defied the recommendation of attaching a battery charger. And it went perfectly OK regardless.

The car is originally VERY powerful with its 3.0L twin turbo and 272 HP, so we weren't sure how much better/faster it could get...
But we had a pleasant surprise ahead of us. After a quick and flawless installation, it was time for the test-drive.
On our way to the spanish autostradas, my dad carefully tested the throttle respons, and after a short sprint, i thought felt a difference in the acceleration, but when he told me he had barely touched the pedal, we started to realize that the project was a success:-)
On the highway the car seemed to have limitless powers. On a 120 - 200km/h sprint, the car shifted from 4th to 5th at about 180km/h, and at 5th gear and 180km/h the acceleration was still grotesque. Incredible!!

I have ordered the new X3 F25, 30d, and cant wait until esstuning has developed a tuning-kit for it:-) I hope I can write the same reviews then
