That is bad ass - thank you for doing these and sharing!

Also that DA is pretty high and someone closer to sea level could get some ever quicker times. Very respectable for your location / elevation

See you're in Roseville - I am staying in Walnut Creek and working in Rodeo this week. Love this area

Small world, I grew up in Redwood City, about 30 minutes from you

Awesome post !!! Broke into the high 3 second 0-60 range (with rollout) with just a piggyback tuner. That is awesome.

Freaking UNREAL how fast these are! Well done man, thank you for sharing this content, you nailed it!

Man you are definitely the real MVP here. Thank you for that. And is that on their latest tune update? I know they came out with a video the other day showing new numbers on the dyno and not sure if they send that to people over a software update or what.

Yes, this is with their latest version and all. I sent multiple logs to them to make sure all was good before I did all the tests. I have to say, it is very impressive!

Did I miss it… did you do a stock or map 0 run for comparison?

Awesome info. Thanks for sharing

I did not record it but best I could do was a 4.66 on a 0-60

Does the program auto-update to the latest flash for maps or does it need to be forced? I have a JB4 I got from a member here that I am waiting to install after a service visit soon

You have to go into the settings and download the latest, its super easy. Just make sure the truck is on but not running

Ignore my post in the other thread. This is what I was expecting! Someone (with rollout) has finally cracked 4.0 - which is what I would have expected on map 3 or higher since it puts out similar numbers to the TRX and probably more hp/tq under the curve. Impressive!

Assuming the last one is a bad launch and/or wheelspin? You are .1 behind map 2 by 10 mph! So, there is more left in it!

How are you launching?

Burger just did a video mixing e85 which is what I was thinking of doing. Mixing ratio can be found online.

Nice! I really want to purchase and install the JB4, but with my truck still in the shop for the second time, I'm worried about it installing it. I spoke with the service manager about if Ram was coming out with a tune and he said he has not heard anything and does not believe they will. He told me only to do a tune after warranty, since it will violate the warranty. I have purchased the AFE catback exhaust system I want to install, and he said no problems with the warranty If I install it. He even said they could install it for me.

I feel like the sweet spot is 3700 RPMs. So I just break it and let off and it does pretty damn good. I don’t use launch control.

Nice numbers Have a few questions if you don’t mind.

So when you did the update you ran it, logged data and sent it in to be looked at?
Who are you sending it to and did they have to do any adjustments?
Where did you place the control JB4 box at?
Did you happen to see what your maxed out boost psi was?
Have you looked on the factory hp & trq data logger to see if your numbers are increasing as you change tunes?

Thanks ahead just curious as to how this JB4 works and if we are able to see this data on our trucks. Mines been working fine and just started messing with it since I’m over a 1000 miles now
