I just put a tymar setup in and I can hear the turbo whistle just a little more than before...... If I put in a 3" downpipe will I be able to hear it even more? Do I need guages if all I have is the tymar setup, downpipe and open exhaust?
My 97 PSD seems to have a bit of a surge in its idle. When just sitting I can tell the engine idles up and down.....this idle variance is so subtle that no-one else would probably notice it. I can see the tach move, but again it isn't much but it does move. Any ideas?
