So, the 4k you though it was limiting at wasn't really 4k?
How was the dyno getting a RPM signal?

I was told this a few weeks ago when I had mine tuned. Interested to see what they say about it.

Don't they normally connect the dyno system to the ECU while tuning? So when watching that compared to the tach they are noticeably off.
Mine was a few hundred RPM off at idle.

It's possible the RPM value in the ECU was accurate, but the output to the tack wasn't. Otherwise, the power numbers would not be correct.

Correct. I watched the Monitor connected to the dyno and saw the RPM's. We also did a quick pull in the parking lot with the laptop hooked up and were able to watch the data log to confirm as well.
The tach is connected to the A19 pin. Not sure what the issue is. Wondering if buying one of those tach adapters would fix this.

Why so low?

Not sure it's possible with the Series 2 ECU, but I wonder if the number of cylinders tach output is optional versus what is in the tune? If the tuner selected 8cyl, the tach would be close to 4k when the engine is at 6.

spoke with AEM this morning and it turns out it is a setting within the software.
The series 2 ECU puts out 4 pulses verus the stock of 6.
If anyone needs the screen shot of how to set this up please send me a PM.

As long as the plenum is blocked and water bypass is capped this hole can be left open?

Yes, I sealed mine with silicone because I am weird about a little sand getting in there. :lol:

I ended up having to drill new holes to mount the rails to the lower plenum. I gently tweaked the crossover hoses and switched them out. All good now. Got my harness back from API with some other goodies, so im going to try to get it all laid out tomorrow.

1 more question for tonight....... What are you guys doing to block off the air assist holes in the tops of the cylinder heads?
