Looking for other modifications that will increase mainly Torque.

Did you tune the TCU as well or are you shifting manually in sport?

Can you provide any tunes for the TCU remotely? I think there would be a lot of us, with ECU remaps and tunes, who could benefit. Hoping it can be done through the OBD II port!

I believe that VAP was working on this, I would reach out to them if they provided you with tune etc.

I worked with ZF to modify the TCM and that was along with a 900Nm upgrade. You can slightly decrease the shifting time, on the V8 WITH a 900Nm transmission, you can then enable launch control but realistically unless you increase the rev limiter, there is no real point in tweaking the TCM. I only increased the rev limiter because I was confident that the decrease in rotating/reciprocating mass, the increase in bore leading to a supersquare engine allowed it safely.

I use https://www.jet-hot.com/ real pros, no BS. Ultra 2500 will do.
Going with Cell 100 cats helps also if one wants to keep cats (mandatory in many states for emission visual inspection). ECU Tuning is required to maximize the benefits and keep the CEL off.
Water/meth injection helps also with cooling, not only to aid in pre-ignition detonation. As a side benefit you also get clean intake valves. I use the Snom MAF/MAP controller unit from Snow Performance. All you will need is two small holes in the upper intake manifold cover and tap the holes.
---- SIDE NOTE for V6 owners ---
I have been reading of people swapping out mid-pipes with ones having an X pipe or with the one from the V8. DON'T! Not only it brings no benefit in terms of power to a V6 but it actually increases the exhaust temps. On V6 engines, the single best way to evacuate hot exhaust is to swap out the muffler with straight pipes (and they sound nice), not raspy as claimed.
