how accurate are the reading on these things. iv had my car remapped to approx 195bhp. not sure on what boost im running at but according to the app it says 22.5psi, which to me seems high but im not sure. also a bit disappointing that the bhp figure is a estimate wheel horse power instead of the engine power.
but besides from a couple of negatives im really happy with the app. the speed reading is a little bit off but to be honest, it might be my clocks that are off and not the app hahaha.
thanks for the recommendations.
