This was on my car. All dyno tests were done on the same dyno as well. 50rwkw is hard to believe, but the dyno does not lie.
The increase was using the Greddy Intake and a 4" core FMIC. Before, it had the stock RB25 side mount and stock intake manifold. It would have made more power, but the turbo was out of steam. It held 10 psig all the way to about 6K, but then fell to 8 psig all the way to 7500.
I am not advertising the AEM EMS, in fact, I would rather no one buy one. Their quality assurance program is non-existant, and they customer support is useless when it comes to any real questions.
