What boost is this running? Does it still have the cat?

The car has all original parts. The cat is on. Nothing is removed or added to the engine. The boost is in the normal range of the original MAP meter ;) . NO DTC is deleted.

What kind of MPG do you get ? TFSI seems nice and easy to tune but is not as economical as I was hoping :(

The max power output with the KO3 is about 280hp with supporting mods. On the other hand with a KO4 conversion 350hp is achievable. There's not much difference between the s3 engine (higher lift cams and stronger connecting rods) and the axx/bwa engine.

I know this is a year old but I believe that 270hp bone stock will cause big fueling problems in the mid range, the fuel pump (hpfp) is cam driven and without uprated internals the fuel pump won't be up to the job. Please correct me if I'm wrong.

250hp on a stock engine is widely accepted by bigger tuning companies.
Max power handling safely 350hp.
