HT-b cam and Fuelx (not pro)

I have a question from a customer that I cant answer: Will the FuelX suffice to use a ht-b cam or do I need the FuelX Pro for that?

I have never used the FuelX (without pro). I have tested the Pro on the BS6 Euro5 with cam only and it worked great. I can manage a maximum of 25% additional fuel thru 7 steps with the switch (steps 1 and 2 allow for less fuel, 3 is neutral i.e. no change in ECU settings, 4 - 10 add successively more fuel up to 25% additional of what the ECU would allow).

But what does the standard FuelX do - and is it sufficient to operate the cam only (without 477 set)?
