Hello,

I have an 2.0l 2003 Bugeye WRX that has been modified with TD05-16G turbo, ACL race bearings, Exedy stage 1 clutch, 2.5l USDM STi fuel pump, SS equal length exhaust with 3" turboback and up pipe, K&N intake kit and an FMIC.

And I was wondering what should I do next, I was planning on getting an COBB accessport. Do you guys think that would be reasonable and would give be considerable power gains? ECU hasn't been tuned after modifying the engine. Yet.

I do occasional track days but still use it as my daily driver, that's why I like the idea of having an accessport and having the chance to change maps.

Thanks in advance and sorry if I missed something important, I am new here.

 

Get it mapped!!! You could be running lean which will do major damage.


Fuel pressure regulator prior to mapping, possibly parallel fuel system if you need to change injectors.

 

Absolutely, definitely get it mapped. You may see some big gains and more importantly you'll prevent it running lean and all the hazards that brings.

 

I am getting it mapped today or tomorrow. Does it make any sense to get an accessport after having it mapped already, or is that unnecessary?
