Desiring more TQ from my AJ126 motor
I have a 2016 F-Type S 3.0L the current mods on it are both upper & lower pulley’s from VAP, Mina gallery thermo intakes, TCU tune (JagMadness), e85 tune (Viezu) and non hp performance mods like go pedal, NGK plugs with heat range of 9, new OEM injectors from Bosch… I plan to upgrade to the v8 MAF housing/sensor and switch to the ps4s I’m currently running DWS06 plus 305’s in the rear BUT what else can I do besides adding a WMI & paramount intercooler to gain better TQ out of my car?

Yep. With all you've already done to it, the best and cheapest solution is probably to get a V8-powered car.
Also, with all you've done you should be pushing close to stock V8 torque (500lb.ft IIRC)

This. You will get huge gains by going with lighter wheels and rotors. The rotors alone can save 10+pounds per corner. This will be a noticeable difference.

I recently switched to slotted & drilled rotors and I’m trying to find 17in rear wheels but the bolt pattern is my dilemma but I plan to switch to carbon fiber seats as well…
You need 19" minimum front wheels to clear the front brake calipers, so putting 17" rears on (they should fit over the relatively puny rear brake calipers) would look a bit dopey!
His car started out as a base, so I assume he has 355mm in front and 18” would fit?
Upgrades are expensive, and you rarely more than a marginal part of them when selling.
Before putting another 10 grand in the car, think about what you could sell it for and what you could buy with the sale + upgrade money
no I have 380mm in the front & 325mm in the back that’s why I want to get 17” in the rear ONLY and stay with 20” in the front I want more tire on the rear
If I may, there's a point where it makes more sense selling what you have and using your upgrade money on a different car.

this is my fun car I have several others, my goal is to build a sleeper v6 that looks OEM on the outside but is fully modded so I rather spend the 10-20k on building it since I know I’m not getting anything close to what I bought it for a year ago.
Increase displacement, swap rods and pistons (consider using ones for the V8), custom fit a tvs 1900. Install a chiller system, use an octane booster, and have the car tuned for 96.
Or as other suggested buy a v8. To make a long story short, I was in your shoes a few years ago.
Had dual pulleys, wmi, tcu tune, forged rims, lithium battery etc.
Was in the middle of adapting the tvs 1900. Unfortunately (luckily) a deer killed my jag so I never finished... I bought a v8 instead
Assuming you can do most of the work yourself; should be within your budget. Biggest expense will be producing a one off intake manifold and intake runners.
There is a chance that the runners can be adapted as is, I was experimenting prior to moving to the v8. But if not you, can probably have a mold made of the runner and just change where the holes for the bolts go.

weight reduction is a waste of time unless your chasing track time, .boosted rickey runs full interior and now going for 9 second quarter mile ,if its street use you wont even use most of that power ,but track you need weight reduction

The V6 also has a shorter stroke than the V8 so you may or may not be able to use V8 rods with V6 pistons.
