My 2019 REWB has an upper pulley, injectors and an E85 tune from Dusterhoff. Runs pretty good given the bad DA’s that we usually have in AZ. Would love to run it in a negative DA to see what it can really do.

That is really good for the DA! Was that at the strip or on the street?
 
That was at the track. As I have gotten older I have much less desire to be running up to and over 130 on the street
What kind of 1/4 mile et did that result in?
 
The first picture is when my car was 100% stock, second one is with a 2.85 upper, pinned 10% lower, jlt intake, blower spacers and blanket, 180 tstat, cat deletes, Fic 1200, HHP dual pumps, CCI driveshaft, pump e85 tune and 305/35-20 mt ss. 2018 Charger with HK sound and sunroof with zero weight taken out.
im swapping over to a 2.70 upper next weekend, curious to see how much it drops the 60-130 time by

You can tell it’s an auto there is no drop in the acceleration.

In the same DA, you can probably get in the 5.4 range with the 2.7 pulley. If you can still manage traction that is. That said, I'm thinking a 20" DR won't cut it anymore with the new pulley.

The car doesn’t “hook” now, I have to start in 3rd and ease into the throttle around 40 for it to have a decent run. If not it spins on the hit and runs 5.9s lol. I don’t turn traction off and the TCS light stays on pretty much all of third gear.
I have some 305/45-17 Et street R going on and skinny’s so I’m hoping they help with traction and less rolling resistance from the skinny’s.

The new tires/wheels will probably drop a couple of tenths alone.

Great data of stock vs modded in almost identical conditions

Thanks man, the funny part was I was telling my buddy I needed to get a pull in with similar DA once the car was “dialed in” and he asked what did it run stock, so I sent him the screenshot and then I realized the DA was practically the same as my current best run lol.
 
I made a hit in super negative DA after installing the jlt cold air, mainly to see how much the negative DA would help the car. Never was able to run the car in similar DA after the jlt install, but it was a little faster in worse DA.
the first slip is the crazy negative DA pull lol and the second is a close comparison with stock airbox

Swapped to a 2.70 pulley and the correct belt size today and this is what it ran, traction doesn’t exist now, basically have to start the pull at 58 mph and it still spins. Can’t turn TCS off it gets sideways as hell, I’m not trying to wreck this thing lol. I wish it would hook up because this DA would really help it out lol

That's serious business! You can tell you're leaving soft and there's quite a bit left on the table. Good shit! Did you re-tune at all?

Yeah I’m having to roll into the throttle, takes a bit of finesse to get it to make a decent hit. Nope, tuner said the pcm would adjust for the difference in boost. The logs show everything is happy still. I’m working on getting a set of 305/45-17 ET street R for the car, not sure they will be enough but hopefully better than these 305/35-20 MT SS
 
For anyone curious what kind of power it took for me to run those 60-130 times. The blue is 2.85 pulley and red is 2.70 pulley View attachment 586287
Traction is the enemy.. mine ran an almost identical time to this with a lot less power. That said,, not nearly as good of DA as your run but definitely better traction than you had. Cant wait to try it out now that my blower is ported. Pretty confident I can pull off a 4.XX
