Received the controller, impressed with how much better the car feels planted. Track & Sport setting is actually much more enjoyable , not bouncing me out of my seat, bumps and imperfections on the road are much less pronounced and can take turns with much more confidence at higher speeds. I'm not a road racer or drag race but its my daily and for me it was worth the purchase. Looking forward to the software release as well.
I installed one of these today on a 2018 Hellcat and am very happy with it. The heavy nose feeling is gone; no nose dive on heavy braking and understeer is gone.. The car actually feels neutral through curvy roads. The Street setting is great for crappy PA roads and yet the front end is stiff when entering turns.

Quick update. I think it is easily worth the money. The street manners and balance of the car a very different.

I went to the drag strip on Monday for some non scientific A/B testing. I had carpet out and secured the controller with two screws to make change overs as quick as possible. First two runs were in the same lane, switched lanes for the final two. First time at track with this car. Foot brake launches at 1500RPM, no roll on, just straight to floorboard. Dead hooked. I’m sure I could have done better, but I need more seat time in this car and wanted to be as consistent as possible for this test.

2021 NB Challenger Redeye 2.62
Stock except AAD drag pack and 20” MT ET Street SS
4725 Race weight with me in car and half a tank of 93
Drive modes all track as advised by Diablosport.

I did six total passes. The first two were just to get comfortable with the car.

Four test passes
1 - Stock controller 1.573 60’
2 - Change to DS controller and hot lap 1.521 60’
3 - Two hour cool down (DA dropped from 700’s to 120’s) DS controller 1.487 60’
4 - Change to stock controller and hot lap 1.536 60’

I used line lock and tried to keep the burnouts as equal as possible. Track conditions were pretty good (had four broken axles and a high 8 second challenger dropped his diff on launch).

I know this is all anecdotal and hardly scientific. The differences in the runs could be attributed to a hundred different factors. This review is worth what you paid for it.

To wrap up, I like it enough that if they have a Black Friday special, ( @MKL_DS ..;) ) I’m buying another for my DD SCWB Charger, instead of swapping the unit back and forth.

Hey, nice write up. My question for you is did you run the car in street suspension usually prior to getting the controller?

So for all the runs you ran in track, right? Did you try the controller with the car in street for suspension?

That's an excellent 60' with running a 20" tire and the ET street SS.

Can you share your E/Ts on the different runs? I'm curious what the improvement in 60 meant on the big end.

Video of the first run with the controller. Big power Trackhawk broke an axle.

First time at track with this car, just turned 1100 miles, so I’ve never run the street suspension setting on the track.

All runs were in track mode.

Don’t have the slips in front of me, however from memory.

1 - 10.72
2 - 10.61 as seen in video
3 - 10.59 thought this should have been better, better 60’ and lower DA, but mysteries of drag racing…lol
4 - can’t remember exactly, but I know it was either 10.66 or 10.68

Trap speed was all high 128 to low 129 which I also think is low for this car in weather this good. Was really hoping 131-132 at least. I’ve seen some run high 133 low 134 stock drivetrain.

Im over all very happy. I weigh 325, so that probably adds a tenth or so over an average size driver.

It's 933 on the diablosport site but the checkout process is broken. It can't find shipping quotes and won't progress without it

Odd, I will look into that, but we sold a few on the web this week so I am not sure what could have happened. Feel free to call in if you wish.
