Too much power with IAS.....

I put on a TMC tune on the 650i GC while waiting for the correct harness for the JB to arrive.....

One question though, the TMC tune also worked well but wondering if any one of you have a tune beyond 500hp+ on a car with IAS?

I put in the TMC tune which is supposed to give 80-100Nm more torque. When I floor the car past 4.5K rpm, the rear end of my GC gets VERY wobbly, which did not happen before the tune.......

I turned down the gain of the TMC box a tad (from position 6 to position 4) and the rear is more stable..... Can it be too much power for the car with IAS to handle?
