Modded airbox, i cut a hole under my box to let tht restriction out and cut the metal plate under it to receive more air into the box.

 

I won't back down ! Lol I'll probably run into him around town again some day ... I'm thinking about ditching my Tahoe 20's and maybe goin to a 17 alloy tahoe wheel with shorter tire to help me out some.. And long tubes in a few weeks. It really was not a bad loss for suffocating my truck and a tuned hemi. Oh it's the cars that come with the 3.92 gears ....

 

Believe it or not, the charger r/t come standard with 2.65 gears, I'm not sure on the srt models. Standard trucks are either 3.55 or 3.92 and the power wagon has 4.56 gears. Keep us posted if you meet up with him again after a retune. Always good to here a good kill story.

 

The only cars that get 3.92's are the Challengers with a 6 speed and 20" wheels ( whether a 5.7 R/T or an SRT8) and then the 18" 6 speeds get 3.73's. The automatic SRT8 models get 3.06's..... The first gear in the NAG1 is 3.54:1 and with a 26" tall tire it's not as horrible as you might think. When I had my 06 Charger SRT I swapped the 09 Getrag differential in it as they had a clutch pack limited slip and larger axle shafts. I kept the stock 3.06 ratio but if I did it again I would have gotten the 3.73's or 3.92's.

I honestly doubt your stock air box is suffocating your truck...... Unless you turbo it that box will flow more CFM than your 4.8 could ever use.

And honestly if you think it sucks that bad just stick the open cone back on.

 

@94vmax ...Well they are are dodges... So there for I don't really care that much, I just vaguely emember a co- worker talking of some new dodge he was shopping for with available 3.92 in some package. ...... Ok so the fluctuation of rpm at the start like its choking would not be caused by that, and the crappy throttle response and loss of power wouldn't either? ...
@ Allan6.0 thanks I'm gonna look into that or a larger hole in the fender to fit that airbox cut out ... Gonna check it out.
@raptor700.... Ya I'm hoping run into him again soon lol ... I almost debated pulling over and swapping the intakes back over lol

 

There are enough people in the world with the stock air box making way more power than you are and the trucks run fine. Did you damage the MAF somehow maybe, or get some oil on it? Maybe try cleaning the sensor first to see if it helps. To try and eliminate the other variable put the open cone back on and see if the problem vanishes or not. I would put money on it having something to do with the mass air flow sensor itself and not the box at all.

 

It's a brand new truck though.... And what should I clean it with ?

 

Electrical contact cleaner will not do any harm and you can get it at most any hardware or electronics store. My old Caprice's LT1 did something similar and started running like a bag at WOT. The open cone design I had let anything and everything onto my air filter and eventually it was enough to foul the MAF. I cleaned it and the problem vanished.

I realize the truck is new but you are also running oiled air filters. Most people ( even like me) can run those forever and never have an issue but like my car did, contamination can cause false readings by scumming over the resistors and not allowing the heat transfer needed to infer air flow.

If you have access to a scan tool you could watch you airflow reading across the MAF and see if it's normal or all over the place.

 

You wanna borrow my 6.2 for a day? Ha

 

Lol I think i will beat ur time in your sig !!
