Renntech ECU tune vs Others?
Just curious if anyone has raced a CLS63 with a Renntech tune against another CLS63 with someone else's tune, curious about the results. Not interested in hearing how expensive Renntech is.

Not all cars make the same exact power so comparing them without doing it on the exact same car would be a waste of time. Too many variables comparingA car to B car. I Have a renntech stage 2 tune dont think its any better than the others on the market. It may not even be as good as now. As a lot of tuners have modified there tune as time has went on. I will never buy another Renntech Product they dont care about anything but making money

Some Renntech tuned cars have beat other tuned cars and vice versa There is not one tune that will beat all others. Im about to flash my car with a different tune because I have catless downpipes and Renntech wont help me get rid of the cel,.They even denied that made catless downpipes outright to me when I have photos of them on my instagram. Not sure what you are trying to figure out but the differences are going to be small
