I havn't installed these (being shipped now or have the parts in my garage) because I have yet to get the new fd, but will I need an ecu with the following modifications? M2 Downpipe, Apex N1 dual, Hks J-spec intake, Fluidyne radiator, Asi Ast.

 

****! I meant this to be in the Rotary Performance forum, sorry! Can someone please move this.

 

its a good idea to have an ecu, just in case it overboosts
