I also went through various ESS tunes on the Z4MC track car (525 VT2 kit) and the E46M I have tuned with them.
The iterations were never due to faulty software. I changed octanes, changed rev limiter, added a valet tune, etc. Each time I got prompt replies. Years after the VT2 kit was purchased they continue to respond quickly to any question I may have. We just made the Z4MC fully catless and I asked about a tune for that, I got an answer the same day.
Years later, due to an issue that has nothing to do with ESS, I used a tuner for my E92 M which is very loved in M3 boards. It took a *month* for them to deliver the tune. One. Month.
It has taken a year and many dozens of emails to get to what I requested and the tuner agreed to prior to purchasing the tune.
I also agree with someone who said they would support used kits, because that would seem like a sound business decision.
Hindsight is indeed 20/20, and years later I think exactly the same as I thought before: ESS is the only company that will supercharge cars I own or manage
