Good evening all!
I have recently fitted a boost gauge to my 2000 S3 APY 210bhp and was a little disapointed with the amount of boost it's producing...
On full chat it over-boosts to just over 10 psi, then drops down to about 9. Is this normal or do I have a problem?
The car has not been re-mapped. It has a green cotton panel filter, forge 008 Diverter valve and that's pretty much it.
Anyone have any ideas?
Cheers in advance!
