thoughts on aem eti vs stillen gen3

SS_Firehawk · 01-05-2013, 08:35 AM

I have no issues with my AEM's. I think the ETI module works. There was no discernible difference between my untuned and tuned numbers. Car got tuned, dyno'd it in similar conditions as my original run and it was the same result. AFR's were within .3 of each other, 9 months apart, and at a different elevation (still a dynojet). I made decent gains on a modified car, but it was including pulleys. 16whp combined gains, I would guesstimate 8-10whp above 6500rpm came from the intakes. The intakes don't neck down at the MAF to "trick" the MAF readings, it stays the same diameter. I don't feel the intake location is a problem. It does not receive direct airflow, but it is not a sealed space, and I have not sucked up any water, even after washes or torrential rains. They come in polished or powder coated gunmetal for the same price and can usually be found for at least $100 cheaper than the G3's.

In my opinion, there is enough evidence to say that the difference after tuning between CAI's is minimal. Lastly, because the ETI modules are still functioning after tuning, the ECU is not going to try and revert what tuning changes were made to the AFR's. I don't know how much of an issue, if at all, but some cars do this on their own.

Hi SS, I have been waiting for you to weigh in as you are a fan of AEM. This really was the point I wanted to make. Each Z has its own personality and from everything I have read pretty much shows that if you get a tune the gains with most CAI are on the upper end of the RPM range and are within a few hp of each other.

I guess if it is about the biggest and best numbers, then be prepared to spend some time and money getting to know your Z...she like a woman. No offense ladies!

The intakes and pulley's were by far best bang for buck improvement I made to the car. Unfortunately, I have to remove both for my twin supercharger upgrade... I have a lot of info my my sig link about it as well. Indeed, these cars do have their own temperments. I'm happy mine worked as well as it did before I decided to do my new project. Nearly every mod I did was never considered the most popular option, some controversial, but my gains definitely show. I made about 50whp over my baseline, I can't complain. Researching is really key, do your homework before opening the wallet. Everyone wants to vouch for a product that works great for them. Cheers to that, spread the word on products that perform.
