Hey guys so I just got a fully stock BA xr6t 2005 4 speed auto 195,000ks and slowly getting parts everyweek as I want to wait to I have all of the stuff I need then get one tune, I have a couple questions 1st one is can I get around 400-500hp off the stock ecu(I'm new to car mods this is my first project car so only just starting to learn about tuning) and what other mods do I need to achieve this, I have the following
-bosch fuel injectors 65lb(650cc)
-turbosmart wastegate actuator 12psi
-walbro 460 fuelpump
-crowcam valve springs
-turbo side intake and battery relocation
-getting either a plazmaman intercooler kit or HDi kit that say they can handle upto 650hp
-getting a custom 4 inch dump to 3.5 straight pipe made(starting of big so I dont have to upgrade in the future)
