Last dyno I went to they left the air temp sensor out in open air claiming that the numbers were inflated when it was put near the air filter (no shіt), and further inflated if they put it by the exhaust manifold (doubly no shіt). That's the way the device was designed. Just because you don't like the numbers it puts out, doesn't mean you mess with the equipment until you're happy. Those air temps are needed for the correction calculations.
Sorry for the rant.

It read 25% too low (because they failed to probe the air temps properly). We have a local Mustang dyno that knows how to run it properly and thank God we can go there.
