- The only tuning company I've ever used so I can't compare to other tuners.
- Great results for my E60 M5 & F06 M6, no regrets other than frequent visits to the gas station which happens to be $4.50 /gal on 91oct.
- Excellent customer support & performance products
- Flash your tune with your computer. Unfortunately, no handheld flasher option
- Can't say they produce the highest Dyno numbers since not all Dynos are created equal. Some produce higher numbers than others, same goes for stock vehicles
What I can say is that they are highly concerned about the longevity of their customer vehicles.
Ex: setting the torque to 700+ on Stage 1 is easy. Set that on a stock clutch, & you'll be replacing it much sooner than expected. Similar rule applies to HP.
