I have a 97 1.8t with 140000 miles. It has an APR chip, 710n valve, new vaccum hoses, just had the tb changer 15000 miles ago and a recent tune up. My car seems to lose a lot of boost after second gear. It picks up fine in first and second and seems to lose boost until I hit 5000 rpms. When I down shift into second from third it has a lot of boost. what could be the problem? Thanks, ADAM

You can totally feel it when changing gears.

If it feels like it is skipping or power surging check the top of your diverter valve. If the plug comes off it will feel weird.
