Since re-installing the turbo an ceramic coated stuff, and wrapping the wastegate and far right down pipe of the header, this bike is definitely running 1-2 bars warmer. For the first times since having the bike, it has hit the top bar on the temp gauge briefly, and unless at highway speeds, the temp bars are about 2 bars higher, now 4, compared to 2 normally down the highway.
My only guess is that the wrapping is somehow inhibiting air flow, though the wastegate is pretty much off to the left side and behind the radiator, and the right down pipe is, well, behind the radiator right side. The wrapping is not touching the radiator.
... I don't like it.
