Camp Beuhring. I get leave in a couple weeks so Im ready for that so i can see my new toy. Bought it while i was here via internet and telephone. This is my second deployment and my last. I as previously deployed to Camp Cropper on the Lib/Vic complex near Baghdad Iraq in 2008.

Darek/Frogslinger thanks for your service overseas guys! 
I myself am active duty (i have not been overseas, since I am in the USCG..Bring it I get crap for it all the time! lol) But seriously thanks for all you guys do over there.
But back on thread topic... I thought about this Sonnax line booster but am curious to know if it's needed w/ my SC Cortex tuner...don't know to much about these sonnax line boosters...

These are the comments from an "expert" on our transmissions, when he was asked a question about the Sonnex.(Comments stolen from another fourm).

These LP boosters "adjust" the sensor reading, making it appear that line pressure is lower than it really is, so the controller will crank up the pressure (until it reads high enough). I don't think a small "adjustment" will hurt much, but I'm not sure it will help either. The controller learns the minimum line pressure needed to avoid clutch slippage. And that's not a single value - the LP is adjusted continuously depending on temperature, throttle opening, gear, etc. So let's say the minimum LP (for a certain set of conditions) is really 50 psi, but your LP booster is faking the sensor by 10 psi. The controller will "learn" the min line pressure to 60 psi and set it there, but in reality you'll still be at 50 psi. So you get no real benefit. There are some times (like during shifts) when we use a fixed LP value, so you would get higher LP at those times, but then the shift parameters (solenoid duty cycles, etc.) are also learned, so again you'll probably just learn those parameters to different values so you get the same shift performance as before. One area that might cause an issue is the fact that we set a fault if the LP sensor reading is too high (greater than 4.75 V I think). At max line pressure in Reverse (250 psi I think) the sensor reading is just below this threshold. So if your booster cranks the voltage up above 4.75 V, you could blow a fault, which would put you into open-loop line pressure control (where it ignores the sensor altogether). This would NOT light the MIL, by the way.
Bottom line: I don't think an LP "booster" will actually do much for you. You may get firmer shifts initially, but then the TCM will re-learn the shift adaptives (to give you smooth shifts with your new, higher line pressure) and you'll be right back where you started. So I wouldn't spend my money on one of these "boosters."

Maybe I will have to get in touch with sonnex and actually figure out if its just a resistor bank...In that case I might just say forget it! I guess derek will be the test here!

Wow I never thought about that. Its a valid point, but I definitely saw a difference in my 3rd gen. It was firm even months after the install. It could be different on the 4th gens tho. I would be curious to see if sonnex has implemented an over voltage into their module to put in in fault 24/7. Then do as you say have a set PSI. Maybe this is why my dealership stated that anything with just just resistors will void the warranty.

I'm no expert but I've been looking around for reviews and what Pull Ya says is generally what I've read. I also saw in some CTD forums that with manufacturing variances and different electronic modules, that in some of the diesels, it was creating problems with the tranny not going into overdrives. Nowhere did I find anyone to claim it damaged anything but some folks had to pull it off to get back to normal shifting. I'm not saying that this will occur with the gassers, just passing information around. I'd love to hear from Gen4 users experiences so that I may consider putting one on.

I have had one installed in my truck for about 3 months.(2010 Dodge 1500 Quad cab 4x4 Hemi) The shifts do not seem to be "hard" as what you would expect from a "shift kit". However, I can tell there is a difference in the shifting under acceleration. The largest difference I have seen is in the automatic downshift when slowing down. It is much more noticeable. I have not had any problems with the Sonnex and I have driven about 5K miles since the installation.(I installed the Sonnex before I read the comments in my above post.)
