Hi all,
I've been tunning my 05 STI very succesfully through the help of GT Autosports using the EcuTek reflash programing. The last dyno run clocked 303 WHP and 330 flbs of torque. Right now I am running a concervative AF ratio of 10.4 This has been accomplished with:

DC Sports equal length header
PDE up pipe and down pipe
DC Sports cat-back exhaust
AEM Cold Air Intake
Perrin 815 cc injectors
Walbro FP
AEM dual stage fuel pressure regulator (50 psi w/vac and 70 psi w/boost)
Blitz sequential boost controler up to 18.5 psi boost
and of course the EcuTek reflash(s) and both dyno and road tunning.

Other accesories not related to power are:

Tein Flex struts with EDFC
Perrin 3 point adjustable front and rear sway bars
Perrin End links

I am very pleased with the performance but really would like a data logger/interface with the current map. I have no need to actually tune the car - I leave that to professionals but would like to view data real time so that I can identify any potentially dangerous "quirks" in the system and go back and review them.

Any thoughts???? Thanks for the help!

 

Are you trying to decide whether to get one or not? I have one, I like it a bunch. Check out my review of it in the Reviews section.
