Blowoffs set at different levels?
So... Another question about something I have noticed on this car.
When hitting boost, and letting off i have a "double" blowoff sound. When I had the car on the lift, i saw 1 Greddy Wastegate, and 1 Tial Wastegate.. (even thought they are one and the same still seemed wierd) I don't believe that they have anything to do with the woosh sound of releasing pressure Correct? Why would I be hearing a double right side left side whoosh.. ?
I appologize if this is a stupid question and appreciate the insite..

that is my main concern..
I am finding that it is way cheaper to buy a already built car, but you spend alot of extra time trying to figure things out and fix what others didn't see as issues!

One question about that..
If i would upgrade from 5lb to 10lb springs would there be any reason i would need to have the car re-tuned? I had a local "tuner" suposedly tell me I would have to and I believe as well as some others that there should be no reason to...

I'm also wondering about the blowoff valve. If there was a wastegate issue, it would be more audiable / evident under load, not after letting off the throttle like the OP asked..
I had an HKS SSQV on my old subaru that made a similar two-stage wooshing sound. Each BOV has a different sound to it!
As for the upgraded wastegate springs from 5lb to 10lb.. Whenever you make any major changes to your engine system like upping the boost, you will always have to compensate with more fuel. Your car will not make this change on its own, your fuel and timing maps will need to be adjusted for the added airflow.
...at least that's how my car works = Þ

The boost would tech. B staying the same.
I just want to get rid of the hesitation I experience
When it is building boost. Boost isover 13 lbs.
I am actually taking the car to maperformance in mpls to have it tuned.... the current tune is not good... hopefully we see a big diff. Plus we don't have 92 octane like it was prev. Tuned on...

Does it make you feel good to put someone down that you don't even know? It sure is a good indicator of your maturity level. Thanks for your post it really contributed to the issue.
