How's your coolant level? How many miles on it? Are your grill shutters closed?

There was no coolant in the reservoir I topped it off, 150k stock everything except when I first got the car i took off the top of the air box and have been running autozone cone air filters since day 1, grill shutters were half closed i forced them all open(frnt bumper is jacked up and a few shutters were out of the mount so I set them back in and opened them all. All fuses are good.

.Everything sounds normal, boost gauge used to go up to the 3rd mark, now i floor the car and it pulls then falls flat with the boost gauge staying steady on the first mark no matter what gear.

You need to find where your coolant leak is. Rent a pressure tester from an auto parts store.

Ac off and reduced power are normal when this happens.

There are a number of common coolant leak points, including:
  • The thin coolant pipe that runs from the expansion bottle to the manifold above the transmission (end fittings can fracture INSIDE)
  • Both heater hose connections at the firewall can leak and the resulting leak tends to get absorbed by the sound absorbing material for a while, so there is little evidence until too late.
