Boost

[Drizz]

Im guessing the 1.8t is a little different from a Vauxhall LET so i cant just adjust the actuator slightly for more boost?
I know it sounds cowboy, but on the Vauxhall engine you could tweak it slightly and it made a fair bit of difference. Im guessing Audis are a bit less neanderthal LOL

As you are facelift, you should have a map sensor too, so if you adjust the actuator the ECU will just use the N75 to eek the boost down to whjat its expecting to see

The setup on these cars is quite clever. No shortcuts or cheap fixes. not sure what the standard injectors flow to either.
