I have a 2020. The pipe before the muffler has a short preganat section about 1' to 1.5' long. What is it if not a resonator?

Had to cut mine to get it out. It's scrap now.

The CAT back or more accurately resonator back will sound better. For a true cat back you need to buy Corsa's resonator delete pipe(this will make the system louder). I'm very happy with my Corsa Sport on my 2020 Ram. The stock system was CATs->Resonator pipe->Muffler->resonator before each...

I know a guy who is a very good mechanic. He told me he puts 20w50 in his trucks...:rolleyes: Some people just don't understand how oil works.

I'm just tired of explaining multiweight oil on forums. I give up. Run whatever you want. But please before you post "I got HEMI tick at xx,ooo miles" please inform us that you ran the WhateverTF oil in your engine. 0w at cold temps will still be thicker than 20w at 200*. It is not/will not...

I got an unlocked ECM through HP Tuners and tuned mine myself with their MPVI2+.

I put Corsa sports on my 07 Vette. I'm very happy with them over the Borla I had years ago on a 97 Trans Am(drone city). I will be putting Corsa sports on my 2020 Ram.

I have the Ram Airflow and the Mish catch can. The catch can does not interface with the CAI. No issue at all.

E locker is more for the off road crowd. Limited slip would be more useful for all around driving.

Synthetic oil will handle the temperature better.

OP, you will be fine changing octane. There is a long term knock table in the ECU that may take some time to adjust when you go back up in octane. Defiantly run higher grades when towing or running the engine hard. Just cursing around you will lose a bit of power and MPG from timing being...

It always floors me when people say they have heard knock. I've seen it on data logs and heard it in old cars I used to have but never on anything newer. Makes me wonder if the knock sensor is bad or the problem has gotten so bad it's beyone the ability of the knock sensors to retard it out.

So far I've been optimizing the base spark tables and the WOT spark tables. Pretty sure I've gained 1 or 2 mpg highway. Not enough mods to worry about fueling. I've tried MDS off for a while, but turned it back on. Need a dyno to tune the VVT so I'm leaving that stock.

Should be find if you remove it before taking it to be serviced

Always a good idea to use a battery tender if any vehicle is going to be sitting for a while.

All actual tuners will require an unlocked ECM. There are some piggyback "tuners" that modify the signal going to the locked ECM. No doubt there is less options with that setup.

I now have an unlocked ecm and HP tuners. Yes, you can change the speed limiter with HP Tuners. Be sure you have tires rated for the speed set.

Yes OP it will be fine to run like that. The throttle body is the only thing that might affect the tune. And that's a might. Most likely the bigger TB will only affect how sensitive the throttle is. Doubt your getting any real power gain from it.

I've had HP Tuners for some time. I used it to tune my 07 Vette. Well I've taken the plunge to tuning my Ram. Ordered an Unlocked ECU from HP Tuners and "The Tuning School" course on Hemi tuning.
