Default Do you see any hesitation around 4000 RPM while on WOT?

If you look at the curves I posted, the HP flattens out around 4K RPM after overboost. This is not great (15-20 HP or so).

Do you think that 1.4bar spikes is good for your turbos?

Default The objective here is very simple. a) normal software does not overboost..

b) GIAC-X software overboosts.

This is a software fix for for the orgin of overboost on GIAC-X. Other software programs do not do this (e.g. APR, AMS). If a software problem caused an overboost, why do think can only be resolved by MBC. Think about it.

Default Do you mean 1.22 bar (17.7 psi)? If so that is normal as GIAC-X is 1.2 bar software.

I think that you should not have any overboost problems as you are running L3 Code. The problem for me was that the previous version of software was spiking to >1.5+ bar (22+ psi).
