RomRaider

Hi All, I have a 2005 USDM Legacy GT 5MT, ROM A2WC522N.

Mods include:

K&N Intake
Tomei UEL Header
Tomei 3 Bolt Catless UP
Invidia Catless DP
Full "Catback" Exhaust
Stock Top Mount
Stock Injectors

*I do NOT have a WBo2*

800-ish ft elevation.
Shell 93 Octane-up to 10% ethanol.

I think that's most of the relevant bits.

I have a working ECUFlash and RomRaider setup already, and would like some input on tuning changes to make, or a suitable base map to start with considering the mods above, because as best as I can tell a lot of you experience knock when going full catless and of course, I'd love to avoid that as much as possible before it gets returned to DD Duty.

TIA!

if your able to post up the map off the car it will make things easier. I think it's the VF40 on your legacy GT which should be fit for about 1.3bar of boost tho you'll need to adjust the timing and AFR properly do make a decent job of it.

As you don't yet have a wideband your not really equipped to tune the car so get onto amazon etc. and order yourself one. Without being able to monitor the AFR's properly your running a big risk over under/overfuelling and causing damage.
