Bc learning mode with traction control?

I am trying with difficulty to get my boost controller to learn the boost curve.

 

It is a profec A and has to see 2 high gear runs to programme itself. The first one isn't a problem (p1)as it just measures the max boost reached. I did a couple of standing start runs in 2nd(auto)the other day and the max it saw was 0.6bar. I then realised that the stock traction control may be affecting it so I switched it off and then got 0.9bar. I thought that the stock traction control cut the power a lot more than this?

 

The p2 mode that learns the boost curve is annoying to say the least. In the instructions I have found it says to lift off the throttle just before the second turbo comes online. I know these can be a pain to programme with sequential turbos but it is possible. I have read somewhere about an alternative learning procedure but can't find much info. Does anyone have any experience with these controllers?
