The car is too lean after about 5500rpm, that's what screwed up the power, I'd bet he was getting knock retard, at redline he's almost around 13.0 A/F --
In an FI car that's bad
If I were you I wouldn't do that very much or you can say bye-bye to your engine.

The car never seen any knock retard. The car is daily driven and runs smooth and perfect.The methanol does a great job to fight detonation at higher boost levels and is a must if not using race gas.

yeah with methonal you can run a little leaner at wot and not get the same level of detonation. I think you need to look at bigger turbo (67) and maybe a set of 02 LS6 springs minimum to control things up top. (Its either running out of turbo or valve float)
What plugs and gap are you running?
