F1 tuning bad choice?

I just got home from a car show. I was offered a good deal on an F1 tuning. The first few times I hit the gas the car accelerated very well and quickly. The third time I tried accelerating the car lost power but came back on in seconds. When the power comes back on it immediately shifts down to second or third while the revs go up, reaching red line on the RPM scale. I had to shift up quick in order to not damage the engine. During a 1 hr drive this happened 6 times. Any thoughts or suggestions? Is there something that can be done to fix this glitch or should I just have them remove the tuning? which tuning is most recommended? Thanks for the help.

Re: F1 tuning bad choice?

I just got a tune on my 05 M3 E46 smg from jailbreak tuning. Rw hp went from 275 to 300. You can go in person or via email. I went in person and watched how they did the magic. Car runs strong with increased power coming on earlier and staying on longer. Going to Laguna Seca end of the month can't wait.
