Ecu remaping, lambda, afr questions

Hello all,

I have 2.0 8v turbo engine from dedra. Its standard.

I want put 3 bar map sensor, walbro 255 fuel pump, and run it od 1.4 bar boost.

Does ecu needs any corrections because any of those mods? or it will just accept all..like 3 bar map, boost... ? I will set afr with wb lambda, so thats not problem.


Also, anyone have experience with removing standard lambda (before catalist one)? Because previous owner cut wires , I caannt find old wires to connect lambda back..
