Rolling road operator manipulating results to keep customer happy.
It happens all the time. (Was it a coincidence that the car achieved 225bhp as standard)
You'll only be left dissapointed if you truelly believe its running 292 and then when the next RR day comes along you only achieve a result of 270-275bhp
You'll then think there is something wrong with your car, chase a fault around that doesn't exist and be dissapointed because you've not achieved the same 292 figure.
All because an operator has fettled with the result to keep you happy, or the rolling road itself is innacurate.
Like i have said before with a FULL mods list your car would be pushing 285bhp max. Your turbo is exactly the same as every other LCR turbo, you've not got a special one
Answer me this, add a FMIC/TIP to your setup and what do you then expect the car to achieve?
But hey dont take my word for it, believe what you want, as long as it says 292 on your reading, then that's all that matters
