Thats a very decent setup, The to4e with the .84 p trim spools up very very Fast, and holds decent power .( I would use only a 50mm or bigger wastegate on that setup or else youll definilty bleed some boost up top ).

and what EMS are you using ?

Apexi power Fc 93-96 spec (8bit)

Apexi power Fc 93-96 spec (8bit)

definilty good choice, dont forget if you can get a brand new engine harness and leading coil.
