Can we add these features for Fk8

Hello my name is John from FK8td.com
Doug suggested I post these requests here.
Individual ignition timing by cylinder offset
If it was available could possibly tune with a bit more power and more reliably. I’ve seen in building and tuning them that the cylinder head the flow on ports 1 and 4 are not the same and often see knock on these cylinders first. Adjusting these cylinders could help.
Ignition timing reduction by gear .
This is for road race application cars. I tune road race cars as well and in 5th and 6th gear load is significantly higher so rather than reducing ignition timing as a whole and it would be more advantageous to be able to reduce ignition timing in higher gears only allowing the car to maintain optimal power wherever possible. I’d rather see this compared to boost reduction as these cars required a lot of boost pressure due to low cfm flow rate of stock cylinder heads.
Volumetric efficiency charts.
This request is because camshafts do not function well without some work arounds. At high boost and especially on ported heads with cams fuel will go lean then rich in particular areas. This is regardless of any maf scaling or settings. It does this on every car with cams and ported head. I’ve had to do some work arounds that do allow the car to correct fueling on Tr2 cams but tr3 cams are a whole other ball game. I’ve had to design my own harness adapter into the flex fuel input and this loses flex fuel capabilities just to run tr3 cams.
Deleting the maf sensor the car does hit target fuel accurately on stock cams and some work arounds in tr2 cams while keeping flex fuel. Many customers not knowing purchase the larger tr3 cams being uneducated.
Live cam timing tuning would be nice as well,
Thank you sincerely
