Anyone in Hertfordshire / North London, favour to ask ?

Anyone in Hertfordshire / North London that could help me out with a tweak to my wastegate on my S40 LPT, standard boost is around 8.7psi, Id like to mildly tweak it to around 10psi

Willing to travel and provide some beer money

You'd not want to travel otherwise it will be roasting hot down there, just makes it a bit more difficult.

:slap: you don`t "tweak to my wastegate" to increase the boost,

You either get it mapped or fit a MBC and bend a rod.
