I'd also like to hear your thoughts on your truck when you get it back. Are you doing anything to help with the additional power/heat (e.g. enhanced brakes and/or cooling)?
The massive stock Brembo's will have no issue with the added power. They brake like my sportbikes...just insane.
It comes with a rad upgrade, which from what I understand, keeps the truck running pretty much like stock, but I guess we'll see.
She baselined a cool 433 RWHP stock today on a Dynapack with the front wheels not powered...very high for this truck...
We are probably looking at just over 620 RWHP when properly tuned...but I can tell you that in stock trim, I've done a 0-60 in under 3.8 in ideal conditions on the road. Not too shabby for a 5300 LB pig...
I have no idea what she'll do S/C'd, but I suspect maybe 3.3's. Even with AWD though - at this type of power, she'll spin tires hard off the line. Tuning will be very critical in this case, as the 6.4's are known to crack pistons without proper tuning.
This is about the best truck I have ever owned...in every way. It blows the X5 and Cayenne away IMO. Interior finish is on par with trucks at 2x the price...and the only way I can describe the sound of that engine/ exhaust is....think twin Merc Marine 502's on the open water. It sounds the same, only with less volume.
