I was lucky enough to come across a brand new unit so no cracks at the moment but after reading that the unit you have is only at 20k i am starting to regret choosing the VF48 over the 18G that will probably change once i have had it mapped

Well after chatting with my mapper today i will definitely be going for a meth mix map I am also debating on a fmic even though the tmic is more than capable of the power i will be running

Well it was mapped over the weekend and the end result was 341bhp-301torque with a slightly under 20% meth mix apparently my 2.5 system of prodrive sportscat, standard centre section and genome backbox is being very restrictive so i need to go 3" now.

Spool wise we are only talking 100's of rpms difference so very marginal and on the road I have driven both and the 34 felt a noticeable amount quicker.
In fact a 30/34/35 will all make better torque than 300lbs ft and the power is quite low especially on almost 20% meth mix.

Dont get me wrong i think the vf48 is a great turbo but i was expecting better results than that considering the meth mix. I thought the prodrive exhaust was only restrictive around 390-400bhp?

With VF48 its everything like lucky draw game,someone will make 380bhp and someone will not make 350bhp,your exhaust can be at this,but still think Prodrive backbox still is restricted,but maybe i'm wrong,if you have friend and i would swap backbox on day of mapping.

If you want 350bhp+ AND pass mot emissions you will need a proper 3" race cat from the likes of RCM, H&S or GGR (= expensive!). Even then it will need to be heatwrapped and will be borderline on emissions at much beyond the 350 mark.
The simplest/cheapest option at over 350 is to go decat and find a freindly mot tester. Then you will be able to realise the potential of the turbo and will get the results you're looking for .

VF48 is nicely suited on 2.5L on 2.0STi or WRX its still laggy.
