You're going to cook your engine if you're not careful.
Pyrometers should always be installed pre-turbo, the turbo uses heat to work so the downpipe temp will be much lower, and you've got false readings so to speak.

115 bar injectors were replaced by the 135bar even for NA engines, apparently the USA never got the memo though lol. However the STT turbo kits and the like never bothered altering the pop pressures...

I'm in the process of a turbo conversion, using a Holset HE200WG with water/air intercooler and a souped up IP, so I'm wary of pushing the limits too far
