looking on garretts website there is no GT2530 that I can see so it would be good to know what turbo you have.
the 25 series turbos arent that big .......
a GT2560R is only good to about 340BHP mabey 30BHP more then your stock turbo
a smaller turbo like that will still get boost taper
boost taper can come from the engine just outflowing a turbo higher in the RPMs making it harder for the turbo to keep up (engine is a pump & so is the turbo higher in engine RPM it moves more air then the turbo can keep up with)
I get boost taper from 5500-7000RPM with my GT3271 which is a decent size turbo mabey 2 or 3 PSI
if you are getting .15bar boost drop thats only 2 PSI which isent bad
no T5 dosent automatically adjust fuel mixture find yourself a tuner & get an ECU done up for your car no matter who you use bang for the buck that will yield the greatest gains
take care
