Decat to standard system?

[seanieb]

Is a full system really needed or would just the highflow downpipe fitted to standard system get the same results after remap?

[rich83]

It depends on what results you are after.

[seanieb]

I know standard stage 1s tend to make around 240-250hp so would a downpipe and cai make 15-20 more?

[rich83]

It has the potential too but you’ll run out of fuel between 250-260 so you would probably need an upgraded fuel pump (and upgraded intercooler and intake) if 270bhp is your target

off topic, what calipers are those in your sig?

[rich83]

DB9. Same as TTRS

Mine made 270 on the R-Tech rollers, just with a full BCS exhaust and Pipercross panel filter. But it put the standard fuel pump right on the limit - fuel cuts were just round the corner. Loba pump sorted that and also made it a much nicer car in terms of power delivery.

Bottom line - if you want a strong and reliable 270bhp from a k03 TFSI, get an uprated pump.

Same applies to the K04 engines.  The crazy midrange torque the TFSI engines are capable of is only possible with an uprated HPFP.
