Second one, my car almost wants to die if you push the clutch at like 4K and let the rpms drop. Is there any sort of decel setting or a slightly raised rpm if the car isn't at 0 mph.
Third and the most important, when driveing the car off boost and just lightly accelerating, right at 4600+ RPM the car goes super lean like 20:1 afr and I have already added in like 15% of fuel to try to allevate the problem with no success. This concerns me a ton. Did I happen to miss a setting? I am sure I will have a million more questions soon.

The tip-in stuff is the TPS1 and TPS2 parameters, try increasing the TPS1 and see if the response improves. You need to have the idle and low throttle ranges tuned first, and tune the response last. Adding a few % to the mid load page, at 800 rpm and 1200 rpm can help the tip in as well.
For the decel stuff, watch the STFT (short term fuel trim) and see if its lean, also let me know what the LTFTs are doing.
On the high RPM stuff, where are you "adding fuel"? (which setting) What are your trims doing when this happens?
