did the VAIS fix today and now at 2000-2500rpm (only in drive) there is a whistle its a quiet wistle but it can be heard without the radio on.. i tightened down the screws on the VAIS control box but still a whistle.

any ideas what it could be from, i did remove the Throttle body spacer could that be causeing it?

 

it is from removing the plate between the tb and manifold. even with a stock intake, it will be noticeable and with an intake it is very pronounced.

 

thanks then i dont need to worry!
