a question for any good mappers
 

over the years i have heard a lot of good news about what can be atcheaved with the standered sti 8 ecu and the ecutek remaps.but my question is at what power level can be had before having to go to an aftermarket ecu.a little info on my engine spec,2.5cdb forged internals,md321t+ turbo,tubular headers,3in full decat exhaust,aps front mount,k+n typhoon,walbro fuel pump, and running on 10 percent methanol,and a few other bits and bobs but you get the idea.so roughly what bhp should i be able to get to on the ecutek before changing the ecu.thanks.

late 400s roughly.. although with modern after market stuff at that level of tune make the whole package gel together very well.
