hey
now have been on dyno two times.

firts time try to get so much out as can with DPF.
results are: about 320-325hp and about 660nm.can get more but then DPF start get dirty very very fast.so i do not beliewe some countryes cars have so much power with DPF.maybe get little bit more=more shit to DPF and dyno shows more than here...

second time DPF away,3inch downpipe.
361hp and 780nm.now propblem is boost start increasing itself after 3000rpm=wastegate too small.

next:
have to increase downpipe size to 3,5inch and exhaust pipe to 2x2,5inch.
port westgate.
this way could get broken 400hp.torgue to higher rpms maybe also more.not down because gearbox.
