Another thing I noticed months ago but never thought to post!
Do you guys get variable max boost according to the gear you are in? I turn my knob according to forth gear pulls and currently have it at 18psi for forth gear but in fifth I get around 20psi and in third I get a little less than 18psi! Is this normal??

Yes that is normal, with any boost controller or wide open wastgate. The reason is that the load factor on the turbos causes the wasgate to open slower. I could hit 1.9 bar on a fourth gear pull on the stock twins. This is the reason some like to dyno is fith gear.
