View Full Version : boost preblem

04-22-2008, 07:33 PM
on my 2001 A4 1.8T i'm having a problem with boost, i have a revo chip, the boost spikes to 20psi and starts droping and it only holds at aound 11-12 psi.
my mods are revo stage 1, FMIC, turbosmart dv.
MY vac at idle is sitting around 18-20.
replaced my n75 valve and it is still the same.

one thing that i noticed, after i replaced the N75 valve i took the car for a blast around the block, when i got back my manifold was glowing red, is that normal or is it indicating something???

any thoughts on this?

thank you
