Im not sure if this is a problem or what but when I first start the car I get 18 in vac, and it will max out about 20psi when I get on it. When I turn the car off and start it up again, my vacuum is up to 10 and boost maxes out at 25 which is where I like it, and sometimes the vacuum will be even higher after restarting and boost just about hits 30psi! My gauges work perfectly and I can tell the difference with the different boost levels. Bought the car from a dealership so they didnt know jack about the car, I dont know what this car has, what kind of turbo, I know its chipped, its got a blow off valve and runs mafless. Any ideas on what is happening?
