I just received my 1M tune from ESS Tuning today and used their Direct Flasher to download it. The process is very simple and easy to follow. A cool feature is that I can flash the car back to stock within minutes. This is a nice option to have before a dealer visit if needed!
I have the production version of their 1M tune and it has significantly increased the power, according to my butt dyno. The power in the 1M in low rpm is very strong right out of the box, but with this tune it is stepped up slightly and then the power really comes on strong at 3000 and above. It now keeps you pinned in the seat all the way to redline!!! The power delivery feels more linear towards redline and pulls hard and fast up the hills by my house.
It has only been installed for couple hours, so more review details to come and dyno numbers to come soon too!
