Smaller numbers bigger turbine ie slower spool.

I would find out what rpm it starts surging up to, and just lower that value. If it's at 55k and it hits 80k then comes back down, you know that range needs to be lower.

Any guidance as to what values to change and what to change them too?

Truck runs great everywhere but light throttle cruising. Doesn't matter the speed. 10mph through the neighborhood it surges boost up and down and freeway same thing

I set your box to my custom curve as per our conversation, so you won't be able to alter the curve since it is set to use eeprom values on startup.

You'll need to get in on it through the app and either update the values in eeprom or set it to not use those values, and then it'll default back to the jumpers, which you can man handle.

Default pin is 9220, you can view the app on google play : https://play.google.com/store/apps/details?id=com.devnull.lbb&ah=tjuL05xs8ST5MKrVQjh6KcEcAj4

They will need to opt-in on the beta testing here : https://play.google.com/apps/testing/com.devnull.lbb

I have not been able to get access to an android device yet. Planning on meeting up with someone this weekend. Just wanted to get my ducks in a row for when I do use the app since I will only have use of it for a few hours. Unfortunately I have to drive to Colorado to use the phone. Everyone I know around me used iPhones.

Is the app pretty self explanatory as to what to do? Suggestions?

I was going to open the box this afternoon and try to move the jumpers on the rpm curve setting and see if that helps at all.

Once again any guidance would be much appreciated.

Have you connected the Bluetooth app yet ? Probably just need to loosen the curve

So just finished my 2001 cummins swap into my 2002 f350 and need some help with the turbo. My truck is running
New SO VP44 pump
7x.095 Sac injectors
Quadzilla v2
4" exhaust
ZF6 manual trans with dual disc valair.

So far I'm loving the truck but feel I need to do some tuning on the turbo or maybe I have something wrong. At light throttle steady speed the turbo will drop to 0-5psi then surge up to 20-25psi then back down, back and forth. It's very annoying. If I step into the throttle harder it builds boost really fast, pegging my 40psi guage and pulls hard. It just seems like it's either building max boost or building nothing.

I wired up the "cruise" setting and it is a lot more linear, builds boost related to throttle input and load up to about 10psi. I don't experience the surging like I do in the normal mode. Not sure if that is helpful or not.

We are getting ready to pull our 32" gooseneck loaded down, to Colorado and would really like to have the turbo working at its best. Does anyone have suggestions that could help me?

Yeah, that's what I'm thinking as well.. since i have the 4th gen manifold I have on facing down, and I'd put one at a 45* upward, but perhaps moved forward a little bit.

What do you think of the idea of parallel hot sides and series cold sides?  Think it could work?

My idea was just to make a V adapter. Cut the manifold flange off completely. Weld a an outlet sideways with your V cut. So one is up and one is down, angled at your leisure. Then it's as simple as routing a few oil lines, and complicated as a Y pipe to exhaust.
