Righto, i did up a quick graph of 115 to see before and after i fixed the leak.
Broken lines Red and Green = requested boost.
Solid Red and Green lines = Actual boost.
So Green = Before and Red = After
You can see after my adjustments the solid Red line boosts alot higher as opposed the the solid green line.

And yes i am a nerd
I love doing stuff like this ...
I think you will find the spike will die down as the ECU relearns its parameters to smooth out the overboosting...
BHP / TORQUE curve on my LC was smoother on the same rollers after a few weeks of driving than when the car was originally mapped. Which I think is down to the ECU.
