The current limitation isn't the ECU. It's the stock MAF. That can be over come with an EVO 8 or 9 MAF though. I know mellon has run 700+awhp with that MAF.

Hopefully this is out before I get my car going again this summer. Hate to compromise with piggybacks or spend the coin on AEM if this will be done in the next 3-6 months.

I've got 13t's at 18psi, and Evo560s. Should be good for ~400-420whp. I think its still in the cards that all of us are going to meet up in St. Louis at Von's place to prove the swapable ECU.

It's really tempting to rack up $2500 on my credit card for a set of DR650 billets for my 99 and show everyone the stock ECU is just as good as AEM.

I think everyone knows that a flashable 99 can be as good as an aftermarket standalone. It's just that most of us don't have flashable ecu's.

So go out and buy one then...

Here are the graphs from my latest 560 run at 18psi. My boost is def falling off to 16psi at redline, I'm already searching for some WRX actuators with 9psi springs so I can transplant those and take care of the problem.

Anyway, graphs and maps.
