2005 SS S/C . 107 000KMs So I have a Few concerns....

1st. I dont think Im gettin as Much Boost As I used to... If i rememeber Correctly befor Pushing like 3000Rpm My Boost gage Would normaly Just Be passing HALF Like 0 KPA. and if I woot Her Would Almost reach the +70 KPA .. I know Its canadaian Its KPA not PSI i Wish it was PSI!!!.. As Now if I push 3000RPM she doesnt quite reach the 0 Mark / Half way... and at WOOT it seems Like it only gose 3/4 of the way roughly +50 kpa iI guesse..

2nd Problem ive been having Is once the car Is warmed up an Been driving for atleast 20 mins. then as soon as I put in Park Car or Put car in Nutral It Dose The RPM Jump 500-1500 Only In park and nurtal. The second I put in back into Drive It Idles Fine.... (Once thiers torqe)

 

check to see if you blew off any vaccumm lines when you went to boost, and make sure they are all zip-tied at the fittings.
