After driving it around more tonight, I can offer these observations ~
- There's definitely a better "Connection" between the engine and the ground as the throttle/engine presents with more responsiveness (Does that make sense?). There's a new-found notice of slight engine-braking when letting off the throttle. I'm having to re-learn some aspects of driving normally with the new throttle response.
- Not sure how to word it . . . . . . The waste-gate controller is set to 38psig. Historically, that's where it hung under full throttle. I'm all of the sudden able to push the boost up to 40psig, maybe 41, or 42 even. There's a marked increase in turbo-bark with letting off a full throttle quickly. I can hear a new low tone in the in-cab sound of the exhaust system (remember, it's a quiet system).
- While technically, I didn't change anything about the valve-body this time, the transmission seems to be shifting a bit early under a full throttle. I realize that with the OEM converter being so loose, I was "blowing through" a good deal, so it may be I just need to re-learn it all. I dunno. It seems the engine wound-up a little tighter before and perhaps was better realizing the HP peak.
(EDIT: Tweaking the TV cable corrected the shift-point mess)
It's funny how literal the term "Seat-Of-The-Pants" really is when judging subtle changes as such. My SOTP gauge is all the more skewed with the new transmission mounts. I can tell a BIG difference in the "tightness" of the drivetrain's connection to the truck.

That being said, I eventually broke the intermediate shaft (This past start of spring or so '10). I had the good folks at SunCoast open up the converter, clean it and "tighten" it a little. Doing so better placed the stall in relation to where the engine's torque peak is.
At this point, I don't know that it could get any better (the converter).
I do know I couldn't get any better customer support regarding the converter and the trans for that matter. Erny (the Chrysler trans guy) listened to my feedback about the truck/trans and what I wanted and working with their converter guy, was able to get it just right as far as I'm concerned.

i dont understand what the best balance point is for spooling the turbo VS. too low of a stall.and putting the power to the ground.
does anyone know what differences the stators and internals are between brands..actual knowlege not opinions..
BD claims to have their own and TCS as well........how much difference could they all be??
$950-$550......................are the internals that different.
and on a side note bd's new "diverter "valve would solve any spooling issues.
so the tightest convertor you would think is the best choice.

yep sure am. for the price, don't think i could go wrong with it and i've had good luck with ATS parts so far. I wanna at least get a shift kit and torque converter in before i put the 47rh in.
