99pa is 0psi so you must be getting boost pressure as you're getting 18psi when driving.
Google tells me 3.65 psi is 0.2516586 bar18psi - 14.3psi = 3.65psi of boost
I swear someone has been a bit cheeky and edited posts....With ambient of 99kpa and a boost to 125 kpa = 26kpa boost = 3.7psi boost
No it's not, it's 14.35psi 18psi - 14.3psi = 3.65psi of boost
