This is an unbiased review of both controllers available at the market right now.
The HTG GCU was my first one and it just didn't work as they promised, more than 1 year trying to tune it, multiple broken Firmwares and a gearbox later I had given up
Now it runs a Turbolamik TCU and it is just amazing, no more laptops where a passenger should be, no tuning necessary, it just works.
