In the 20D case it is rated at 237HP. Also told that it was not sure all cars could reach this due to error messages.
I am now using the same box (with different settings based on recommendations from RC) on a E70 30D (8 gear) - can't recall setting. He told me that the box will bring it from 245HP to around 295HP (+20%) based on their recommended new default setting (I can tell you that this is something you can feel).
The new 30D has standard 258HP, the box is set at +20% from RC meaning around 310HP (stock setting) and not 331. But 310HP is not bad either. The new X5 30D is already 0.7 sec faster from 0 - 100km/h than the E70. With the box my E70 is significant faster than stock (7.6 sec) - actually drives up equally to my friends X6 40D (which is 1.0 sec faster than stock E70 30D. I would imaging a F15 30D/35D with around 310HP will do 0-100 km/h in around 6.2-6.3
Btw, I have now used the RC box for app 50K (X3) and 20K (X5) without any single error - I take if off for service and I don't think BMW have ever notched
Good luck

Just found the following on German tuber Hartge's webpage
E70 8speed 245HP -> Tune brings to 290HP/640NM (more or less as default setting with RC). 0-200km/h down from 51.4 sec to 35.3 sec
F15 30D 8 speed 258HP -> Tune brings to 302HP/655NM
80-200km/h (not same as with the E70) down from 32.2 sec to 27.4sec
Btw, they rate the std X6 40D (306HP/600NM 8 speed) to 35.4 sec 0-200km/h - same as the tuned E70 30D, so my feeling when racing against my buddy's X6 was right
