2003 WRX

Custom Intake
GrimmSpeed EBC
Catless up/downpipe
3'' catback

Power reading: Virtual Dyno
Octane: 93
Temperate: 65 degrees
Boost: 17.5 psi to 14 psi taper
Launch Control: Yes :spin:

Due to the cool temps this night the car was able to put out some higher numbers then what I am used too on this setup. Delta weight was just the driver and myself. Numbers were high enough that I went back and re-did the runs a few times. Car is going to need a fuel pump (Getting replaced asap) as there were some fuel inconsistencies from time to time and then we will adjust the tune.

will I be able to beat this with a similar set up but with a catted downpipe, and a walboro already installed?

We can see, each car is a little different at this age based on overall health.

Nick's wagon made higher numbers but he has a FMIC/walbro/ebay header.

cool. I have the fuel pump and Grimmspeed EBCS ordered and on its way, and I'll be installing a 2004 STI uppipe this week.

I'm hoping to be able to call you soon to set something up :D

Just call or email for best response :D. We've been very busy and not on the forums as much moving into our new shop.

Got the Walbro and front o2 sensor a few months back, and an APS 65 on there too. Need to come back for another tune. I want some more torque (closer to the 270 range), anything I should look into before coming back?

Intercooler or header. But both will slow throttle response and shift power to the right.

Torque peak isn't a number id chase. Look into broadening the curve with a vf or bigger. Much more enjoyable.

Have a line for a JDM intercooler. Not sure I want to do headers. But I am looking at turbos.
