Talking Help this Evo...with file and photo.

Hi everyone, I'm Simon and I write from the 'Italy ... now is 2 years that I follow and I learned a lot ...
I am speaking of the car was mine and now she needs your help!
Spec: Evo 8 2005 turbo-back exhaust with 76mm high-flow air filter, HKS SQV blow off, and this mapping I made with wideband and lots of patience!
Now the problem is: I can not maintain a constant pressure turbo ... and consequently the power curve has a peak between 3500-3700 rpm and then drops suddenly!
I tried to change various parameters of the turbo, but nothing has changed! ... What's wrong?
Thanks for the help ... the map is as follows ...

I havn't looked at the ROM.

but get a 3port boost solenoid and retune...

stock turbo will fall over above 5500rpm, regardless..
