I lol’ed
There are a few similar threads on evom and gvr4…people losing anywhere from 4-10psi based on humidity.
The car would previously make 20lbs in 1st, since water is expelled from the air as its compressed, if the car has more time to compress the air, I should hit 20psi, right? car is spiking 19 in 3rd (long gear, lots of time to make boost). On top of that I actually tested it, and am 100% sure its not a boost leak at this point.
