[eltracer]

Ok my stock psi was at 10psi then I did the free mods and raised it to 12psi. All of a sudden My psi has dropped to 9 psi. Car's fluids are nice new and sounds normal. what do you guys think is wrong? Also some time.not much, but my psi will go back to 12psi for a day or two then go back down again!! It suck three psi is a big power loss.

our cars are very sensitive to weather changes, our cars will run a little more boost and run leaner when its 20 degrees colder then the day before, does it feels like it might be just from the cold to warm changes? its possible that may be all it is.
