Hello.
Welcome to the forum m8!

Your AUM will be (should be from the factory) using the k03s turbo which can shift a greater volume of air compared to the older k03 turbo. Our spec1 remap should give you figures of around 210bhp/240lbft if your engine is running spot on. A small boost leak, or a naff maf can eat away at a huge chiunk of the power.
Your filter and exhaust should help the turbo spool up a bit quicker a d give your small amount of extra mid range power. If you looking for more power, you will need to get a sports cat fitted or de-cat which should take our spec1 remap upto around 225+bhp 250+lbft.
When you say dump valve do you mean the blow off type?
