Resolved!!!!!!
After hours and hours of trial and error, my issue is resolved!!!
It was in fact a tuning issue. The underdrive was pulsing on and off. This is a known issue on 2019+ trucks. Be very selective on who you choose for tuning, especially 68rfe tuning! New trans tune fixed all my...
Traded the truck, so no need for this anymore.
Used for less than 5,000 miles.
Located in Ripley, WV but travel to the Pittsburgh, PA area at least once a week.
$275
I ran 37” Toyo RT’s for the first 25k miles of my trucks life and have zero complaints.
Recently installed 37” BFG MT KM3’s and Im not exactly thrilled with them. They are much louder, they hold gravel worse than any tire I’ve ever had, and the road manners are far worse than the Toyos.
Still no resolve. I’ve changed the pressure sensor, pulled the Valvebody and installed new filters and the surging is getting worse every time I drive the truck.
After data logging it looks like the shutter occurs when the trans pressure drops abruptly from 240ish down below 200 and immediately goes right back up. It will jump back and forth the entire time coasting in 6th gear.
Same tuner for the previous street tune, new race tune was flashed when I installed the trans parts and that's when I noticed the issue. I switched back to the street tune and it doesn't do it anymore. Tuner is thinking its a rail pressure issue.
Just finished installing the BD protect68 kit and ATS accumulator pistons in my 2020 Ram 3500 mega. Install was easy/straightforward. I used the BD gasket plate and a set of billet accumulators from ATS, along with the overdrive shim (washer) from Sonnax, added a BD Diesel deep sump pan and...
Swapped the Toyo RT 37 12.50 18s for BFG MT KM3s 37 13.50 18.
A few notes:
13.50s rub more everywhere! They are 1/2” taller and almost an inch wider than the RT’s (measuring both when new)
The BFG holds more rocks than you could ever count, while the Toyos didn't at all.
Ride quality is better...
I ditched the Bilsteins for these. Normally I would never be this excited to recommend a RC product but they outperform both the Fox 2.0 and the Bilstein. They are 1.5” longer than the stock shocks that came on my 3500 factory air ride.
They do allow for about 1” adjustment up on down. But as @jpidgie stated, when you increase pressure to achieve ride height it makes for a rough ride.
I plan to install a 1” airbag spacer and modify the adjustable links to allow for min pressure in the bags in hopes for a softer ride
Bilstein coils and shocks up front about 2 - 2.5” lift
Revel performance adjustable links in rear set to 1/2” to level the truck out.
18” wheels and 37” tires
Rides like stock
I’d like to try air bag spacers in the rear. Leave everything else alone and throw the spacers in. I believe it will...
