I have the Taccom system with their two piece polymer buffer and their reduced strength spring.  With your adjustable gas block and titanium BCG, you should be able to tune the gas to achieve your goals.  I have the Faxon Gunner BCG (similar weight as yours) and the SLR Sentry 6 adjustable gas block and have tuned it to operate very optimally.  No issues!

ETA: Not that you asked for this, but I wrote up my experience in tuning my gas block.  Thought it could be helpful to you.

One of the most overlooked aspects of the AR15's operating system is the role the buffer plays.

AR15s are gassed hard and undersprung since the design was engineered around a small, fast-burning IMR stick powder originally that only needed a lightweight spring guide (Edgewater buffer).  Once the Army Ordnance tried to sabotage the design with ball propellant, a heavier buffer was seen as a way to address this, and the buffer we all know was adopted on the XM16E1/Colt 603/M16A1 to act as a rate reducer to get the gun back to its design envelope of between 650-850rpm.

You need impact and rebound from the bumper on the tail end of the buffer to reverse inertia enough to have sufficient cumulative spring power and inertia mass to strip a fresh cartridge from a fully-loaded magazine, drive it up the ramp, chamber it, and lock the bolt.

A lot of AR15s are on the edge in this regard when looking just at spring rate, so when you dial down your gas with a low mass system, you paint yourself into a narrow window of reliable operation that may be perfect for the temperature conditions you adjusted the system in, but not enough on match day with even a 10° F drop.

This is why military guns are gassed so hard, otherwise they would never pass the Arctic testing regimen up at Grealey in AK.

When you now take a lightweight carrier that violates the 3/1 "rule" Stoner and Sullivan used for carrier/bolt mass, you have less inertia to work with, especially with the standard action spring, which has a lot of variability to it and drag within the RET.

This is why JP made the SCS, to provide a more constant spring rate with different spring and buffer weight options.  You need to get sufficient kiss of the bumper at full rearward carrier travel in order to get the required inertia to cycle the action in the forward momentum stage of the cycle of operations.

You can lose control of your cycle rate also and have excessive kiss, with carrier-over-base malfs because you now are beating the mag spring's ability to life the cartridge stack.

Things start to get circular away from your control as you attempt to fix one problem with the next band aid, and may find yourself in a position where you are happy to just be done with it during a rare string of fire where it functioned, but malfunction is around the corner.

To really diagnose your cyclic performance, high speed video is very helpful and an optimally-timed AR15 is a beautiful rifle to run through string after string of fire on a shot timer.  Modern smart phone cameras at Gen 6 may be helpful in acting as a high speed camera if you have one.
