I don't know that I'm running lean. I haven't measured it.

I'm hoping that someone on here has. I know a lot of people are running the 9.5psi NST pulley with the Turbo BPV, and I've heard stories of blown engines at redline.

I've heard that the trd tune is rich and that you can run the extra boost with it. I've also heard that you can't. I'm just looking for someone to give a definitive answer.

I read all this thing about the CAI too, but decided to prove it by my self with a wideband. First, when I installed the S/C, stock pulley, not CAI, the car runs rich. Second modification was the NST 9.5 psi pulley, the wideband still rich. Third was the CAI, the wideband still, running rich. But cooler air, then tuned and have to lean it a little more to get more power, but conservative tune because this is a daily use car. Conclusion, TRD reflash runs rich, but every mod like this that you do, you have to monitor your a/f ratios, no matter you are FI or NA.

Im still trying to decide between e manage ultimate and AEM F/IC

Any help ????

Basically i want something reliable and will get the job done ?
