FTVB or not to be...........
I'm sure this question has been bounced around, and I searched a bit, but - -
do we want to program for a transmissions poor function or upgrade with custom parts. Greg has said modified parts, Mike says???
I have an Xcal2 coming in a few weeks, programmed for my stock trans, but we can reprogram -
Thanx, Burns

Hi ONELOWF,
It's really a matter of what you want to accomplish.
I think the best way to explain it is like this - if you want the tranny to be safely capable of shifting quick & firm enough to "chirp" the tires during a FULL-THROTTLE 1-2 upshift on the "performance" tunes, then the safest & best way to do that is with a combination of both Greg's FTVB and our custom tuning changes. And it will still shift nice & smooth in "normal" driving, for example.
The FTVB is going to make the tranny physically capable of filling the oncoming clutch quicker - and that will make the transmission shift quicker & tighter all by itself, that is true - but that isn't as progressive as it really should be IMHO, and doesn't do anything for all the other shift characteristics which can certainly use a good deal of improvement.
Now if you just want a cleaner, tighter shift with less slippage, that is easily accomplished safely with our tuning alone -
So which do you pick?
Personally, if it were my truck, I prefer the combination of both - and that is exactly what we have done with our 2004 F-150, for example, we run Greg's FTVB along with our tuning, and it is nice and progressive - nice & smooth at light throttle, a bit firmer at mid-throttle, and tire-chirping when you drop the hammer - that's how I like to set the tuning up, so that the shift firmness levels are completely linear & progressive. Light at light throttle, and then as you give it progressively more and more throttle, have the shifting get firmer & quicker (shorter duration). That way you can drive it in any weather with no problems, anyone can drive the vehicle as it's nice & predictable - yet when you nail the throttle to the floor, it'll chirp the tires on a WOT 1-2 - just like it should for us performance guys.
We keep Greg's FTVB's in stock all the time, so we can easily just add that to your order if you want to, just let us know - and we do need to know if you're going to do something like a shift kit or Greg's FTVB when we do the tuning, as there are a number of things we do differently if a shift kit or the FTVB is in there, OK?
