DMS Automotive Power upgrades

I can only speak from my own experience back in 2018 with my gen 1 CS, which was a positive one. The guys create bespoke maps, have their own rolling road etc, and had some impressive machinery in their workshop while I was there, included some Porsche products. They seemed to tailor their maps to the car, it's condition etc (i.e. they'll go further with a car that's in fine nick, with a healthy engine etc, versus one that is not). I had outputs from their rolling road, which I compared to results from a session on Regal Motorsports rolling road a few months later....basically identical. Another chap on the Cayman forum (Andrew T) had a less positive experience as wasn't happy with the increase in performance (981, GTS perhaps?), the crew at DMS tried a few different things, then in the end shook hands and refunded his money.
 
I had a re-map on my 981 Boxster GTS in May 2018. The base overall output of 333bhp was remapped to 369bhp - I could have opted for more, but I wanted to optimise mid-range for real world driving. I noticed a big difference over 3,000 to 5,000 rpm with a 12-17% improvement in torque and power which was plotted on a graph against the standard output curve.
DMS offer a service to change back to the original spec should you need this option and then re-instate. I had reason to do this six months ago and this was catered for; no quibbles.
Overall, I thought a little expensive, but in my experience, I can recommended the DMS service.
