Around 400 miles later and with hpde event ahead Ive rolled back to stock. Very fast process
Detonation is immediately gone. I can use full range of gas pedal again.
I will re-install PP2 and play with it a little more later when I will be able to drive it for more time hoping it might adapt.
Switching to pp2 and back I'd say that long term improvement over stock is better driveability in 6th gear, better pedal response and fuel economy. Also, engine is feeling much better in 5000rpm to redline rpm range.
Since I would not push the car once I realized detonation was there - I. cannot claim I felt day to day power bump. With pp2 you feel more potential, but being unable to hit the floor and unleash it, you just do not get it. Stock feels like less power, but you can push the pedal all the way down and enjoy it.
Under the hood - they could do better job with intake cover. Sealing on top and from the side is just a joke. Do not know who designed a side insert to the filter, but it serves zero purpose and is so fragile - will not survive a couple of filter replacements. Water does make it to the filter from heat extractor area when the car is staying and from the front while driving. It does not make damage, but it does not mean it never will.
Inside cabin noise with stock intake is reduced back to comfortable level. Shelby intake introduces some unpleasant frequencies. Not much, but I learned to hate these specific ones while playing with aftermarket exhaust.
Now, since pp2 is sitting in the garage I will take time and design some better long term sealing around the intake.
P.S. One thing I mised during and after PP2 installation process - due to limited access in my garage I did not disconnect the battery. In theory pcm flashing should reset adaptations, but now I think, what if frpp guys have bugs in their flashing software and do not reset all adaptations? Do not know why it did not come to my mind to disconnect the battery later on. But next time I will install pp2 I will disconnect the battery for long period of time, maybe several times. Who knows, it might force to relearn.
