Exactly. "My airplane is 'likely' not going to explode." Not an approximation I would make without verification. It would have been just as easy, and prudent, to install at least one single cylinder sensor to verify the differential and more prudent to install 5 more to ensure early detection of an injector leak (of which probability of failure increases with accumulated hours - especially with JetA and operating temps on the high side)!"...when it reports 1800f the temps coming out of the cylinders are likely closer to 1350f."
The explanation does seem to be tainted with with optimism.
