I have a stage 3 tune on a 2.3lpt 1999 9-5 so boost is aprox at around 20/18psi when 89 degress outside and I apply the gas (running 92/93). However,I find when I go to wide open throttle for a period of time it will spike to maybe 22psi then starting bleeding down to maybe 10/15 inconsistantly and settle in that range if i just keep the pedal pegged. Is this a sign of bad vaccuum hoses?
I definetly feel a HUGE power difference between fast acceleration (powerful) compared to a long acceleration run (seems like it runs out of umph)
btw the car has the bigger tdo4-15hl turbo and no cat
