I am very happy with it. Even happier with the ARH install. Can't wait to get the car back on the dyno. It pulls very smoothly. No cel in over 200 miles between my son and I driving it. Made sure we did full engine shut downs to let things cool a bit before restarting. I feel Matt and crew hit the bulls eye on the first round. He did btw use the supplied gaskets. ARH has a huge hard to miss red w/black lettering warning sign attached to the new gasket set advising not to use the factory gaskets.
I am hoping to hear more about how you would describe the difference in driving experience, in detail, how is the sound and "feel" different and how noticeable are the additional hp/tq gains and where? The actual dyno number is cool but....

No, you didn't. I have not been able to get loose from work long enough to get the car back to 21st Century so that Matt can do pulls. Hoping for this weekend.
9 hp gain with the aFe CAI. Dyno sheet is in the car and I'm simply too damn tired to go out to the garage to get it. Iirc, there was a gain of about 5 ft pounds in torque. For the $450 I paid for the aFe, it's inexpensive hp and right in line with what we expected. I'm sure the oiled filter would have better gains. Next we will dyno the headers. With luck, this coming weekend. All depends on if Matt has any tunes on the schedule that cancel out.
How about the A/F how did it change?
Be great if you could post some sheets.

Thanks
I'll bet that if you called Matt at 21st he could email the dyno sheet to you. I took a picture of it and tried to up load it. I kept getting some kind of error message about the file type. I finally gave up. As for the a/f ratios, again, I would have to defer to Matt as he is the one that did the dyno pulls. Keep in mind, we did not do a tune. The objective was to simply let the ECM make the necessary adjustments it needs to within what ever the factory parameters are and not throw any codes. So far, so good.

405.3 HP 418.6 Torque
Matt just did the first pull. Letting the car cool down now. Outside temp conditions virtually as the last two times. Fifty with mild overcast sky. Could not ask for better.

What kind of dyno (name) is it? What were the stock numbers?
21st Century has a Dynojet. His stock numbers were 391whp/407wtq. He's since added an AFE intake and ARH mids. He picked up +9/+5 from the intake alone, so that would be 400/412. So apparently the mids are only worth +5/+7?

Second pull 411.2 hp 425.7 torque 😁 Gotta love it !
I was hoping that the mids would be worth more than that.

Oh yeah. At some point down the road, just for grins and giggles, I'd like to change back to the stock air intake. Drive it for a bit to let the ECM re learn the change and then do a couple of more pulls. It would really be interesting to see those numbers.
Thanks for posting your progress and numbers. My setup will be the same but I am going to add E-85 into the mix after the ARH mids.

Sounds about right. All I know is I sure like the way the car sounds and accelerates compared to how it used to be. Driving with the paddles is a real hoot and even drive mode can be scary now. The power comes on so damn quickly with just the slightest tip in on the throttle.
