copied from another post i made on diff forum

I searched and couldn't come up with a conclusion so here it is...

today i went out to pick up some spark plugs and other things from the store... so i turn onto the main street and hit it in first and then shift and slow down to turn... im turning on my street and hit second and see at like 4000 my boost is going over 5 psi... now on idle there is a slight knocking and when i rev after it drops to about 25 vac and when shifting at like 3000 it drops to almost 30 vac. I switched out the spark plugs to new ones... same problem...all hoses connected... we just tuned the car yesterday...i have no wideband in my car so couldn't tell you any a/f ratios... also the wastegate is surging a lil on idle...it starts where its pretty much almost closed and surges a lil open...

updated.....

just went out to check and the car is making a slight ticking noise now along with a slight bog type sound...this is the new sound, different from the first...

 

25 in/hg? That sounds good?

check your oil pressure

 

well now its staying at 21 where i was told it should be...but its still ticking...but maybe im paranoid...just looking for anything to check to make sure my car is still okay...
