Map courve

[Jimmy_GTT]

Can someone post me his map courve during the rev range?

Here is mine:

I have max. boost (237kPa = 20psi) at around 5600rpm. But than pressure drops back with 20-25kPa.
Scoff told me maybe the wastegate causes the problem. Currently I have a 1.1bar wastegate from a Clio 1.5dci and a Hallmans boost controller. (the effect is exactly the same without the boost controller only the curve is a 20kPa below) It was also the same with the std. wastegate + boost controller.

My setup is:
T2/T25 hybrid with 35a/r @turbine side
ktr cam with std. vernier
Carb is corretly adjusted with a wideband.
And a FMIC from a Megane 225.

Thanks

Or maybe a boost curve?
I'd like to see how it should look like when full boost is reached.
(And the best would be if I can see such curve of a car which has a not std. cam for eg. piper 285)

Thanks!
