i have nearly the same setup.
i dont know which ecu do you have. i have power fc l-jetro.

you could be seeing 1.6/1.7 out of your turbos, depending on the capacity of your intercooler.

with those mods you could get to 640/650bhp. above that i think you might need a fuel surge tank

They are a very similar turbo to a 2860r-5 or 2530 except plain bearing.
so 1.5 bar should make 600+ hp/

Im running the same turbos !!!! Im going to run mine at 1.6 bar !!!!
Any higher your creating to much heat in them.
Mine made 610@1.3bar before i rebuilt it there on these turbos.
