so my boost has been what seems to be low. spiking 14-15ish then going to 11-13ish and tapering down as i hit close to 5000 rpm. i told mazda this and they said that is normal? that im only gonna spike 15 then hold lower. but from what ive read on here it seems u guys are spiking 18ish and holding 15. those that have guages and can chime in, are u stock and holding this kind of boost?
