21 Challenger Red-eye Direct connection Stage 2 Completed Dyno results.
I'm scheduled for the Direct Connection Stage 2 installation on May 2nd so I figured it would be cool to get actual before and after results of the outcome rather than take Dodge's word for it (Sorry Tim k 🤣) .
I talked with Josh at HHP last week and he was interested as well. I took it in today for the baseline pulls. My car is Stock as delivered from the factory. It's best 1/4 time to date, on just tires, is 10.16 at 134.26mph with 1.43 60ft.
The pulls were done on a Dyno-jet Dyno, temp was 58', was raining, and DA was about 390ft.
It had its best pull on the first try netting 707whp, with 665 ftlb of torque.

What was strange was that COT protection came on on every pull at about 6k, and when checking my 1/4 mile data logs it doesn't appear to come on at all except the one time I hit rev limiter.
Here is a video of the Pull.
Once the installation is complete next week it will go back on the same Dyno and we'll get both High Octane, and Race Gas tune pulls and I'll post the results here. I am also running it at Cecil County on the 5th so should have actual 1/4 mile times as well.
When completed you will be able to judge for yourself if the DC kits are worth the cost.
Results;
Ok everybody the results are in and I have to say am very impressed, Dodges numbers are very accurate.
Just so we're all on the same page I tried to make it as Apples to Apples before and after comparison as possible.
Josh from HHP did all the pulls on the same DynoJet Dyno using the same settings before and after install. The pulls were done in 6th gear (1to1 gear ratio) for the same length of time.
The weather on before install was 58' with a DA of +390ish vs today's after install of 72' with a DA of +1000ish on same Kestrel 5100 meter.
Fuel used was Sunoco 260 GT, 1/4 tank. COT protection kicked in at around 6000 rpm before install and about 5500 rpm after install (it was warmer today so that probably accounts for the difference)
Here are the results 👍
The Dyno sheet below shows best pre Stage 2 install pull of 707.3 rwhp with 665.1 ftlb of torque and best after Stage 2 install in High Octane mode of 790.69 rwhp with 749.57 ftlbs of torque.

The Stage 2 install netted me a Gain of approximately +83.39 rwhp and +84.47 ftlbs of torque and -3 tenths and + 3mph in the quarter mile so far, while still retaining the remaining 36 months and 56,000 miles of my power train warranty as well 12 months 32,000 miles of my btb warranty.
The other questions we answered, there was No P1400 code detected and the tune and PCM were Not accessible in anyway.
I will be going to a radial prep test session tomorrow and will be going for best ET this time vs a bracket time last outing and hopefully will be in the 9s 😁.
Once I finish the final track testing tomorrow I'll add my opinions on the Stage 2 install including a comparison vs HHPs Stage 1 tune with the same pulley setup with Josh providing actual Dyno pulls on same equipment as well as a price comparison.

What offset do you have for the rear setup? Looking to get something similar or if you can give a link to the exact ones you got that would be great!20.5 welds up front with 175/55/20 Briddgestones up front, and Weld S71 17x10 Beadlocks with MT 305/45/17 ETRs on rear.
