Dear Scoobynet'ers,

Looking at fitting my Dawes I had on my last Impreza (MY00) to my WRX MY03. I would like to know how many others are using it with the standard MY03 (not STi). Also what boost increase are you SAFELY running.

Previously I was very happy with running MY00 + Dawes for over two years. After going much research, mainly here (thanks JB!) I was running circa. 20% increase in boost (just under standard fuel-cut) for reliable operation. Never had it formally measured (didn't want to) but my butt-o-meter felt nearly a 20% increase in power.

Thanks in advance for your feedback,
Steve.

Humm, someone must be running a Dawes on a standard WRX 03...

I seem to remember people had troubles running dawes on MY01+ due to the cat in the up=pipe overheating with increased boost pressure...

Thanks for the feedback so far. It looks like the Dawes is not a very popular mod on the MY03 yet.

If I asked the same question for the MY99/00 that would be a different story.

Ok, the information regarding increased boost may lead to the first CAT getting too hot, and a subsequent CEL I would like to explore further.

Do we think this could be caused because the ECU does not have as much "play" with regards to fueling/ignition as the MY00?

Another way to explore this is to open this thread up to anyone who has an ECUTEK or PPP on their MY03. I know that ECUTEK remaps the standard ECU for improved performance but I think it also increases the boost by around 10-15 percent (hoping that someone can correct this if wrong). So if the boost is increased do we think that the first CAT will also exhibit this problem?

Just to let you know Steve, we can not change the title of the thread once it has been created. Sorry.
