loss of boost? i was ordering from thesaabsite today and added one to my order.
my car has significant boost loss under hard accel (line btwn yellow and red) and i wonder if this could be contributing. altho, the car boosted 3/4 red without the check valve on, so guessing it doesn't really affect boost pressures.
as for the boost loss. guess i should replace all vac lines, blow into them to see if any device is not holding air, and look at boots on intercooler connections. anything else i should look at?
the BPV is no longer in use, as i have a BOV on there, but when i did the blow test it was hissing. would the bad (not in use mind you) BPV be a def place to start first?
thx nick - cheers, neil
