Ive figured i need to have another look at my fueling on this car.. since i get a feeling that something isnt right here..

Ive been running a setup like this:

LAMFA: set up to give me 12.6-13.0 AFR in areas where i want to have access to the engines full power when i request it with the pedal. this as a preemptive approach, to extract maximum power and have a stable mixture even BEFORE there is any actual load.. also a bit richer in the torque peak.

TABGBTS: set at 840.

FBSTABGM is set like oem, like this:
950: 0
970: 0.5
990: 1.0
1050: 1.0

KFDLBTS: is left like oem.

KFFDLBTS: i initially zeroed this whole map.. and have been running with it this way ever since..(bad?)

KFLBTS: is setup to enrich the mixture down to 11.5-12.0 afr if triggerd by high modelled EGT(even activated if KFFDLBTS is zeroed out?)

KFLAMKR: set to enrich the mixture by 1.08 if knock is detected(right?)


this results in a pretty smooth and stable fueling, good power, BUT, i can feel the car hesitating sometimes.
this feels just like when the mixture is enriched too much as with the OEM fueling..
i havent managed to log this phenomenon.. yet.. but if i let off the pedal about 20% the engine pulls harder again.. and then i give it WOT and this time there is no hestitation until revlimit.

ive been trying to figure out if this is boost related, and if im infact requesting a bit too much boost too early..
if this issue shows only when IATs are high.. and the funny thing is, when the engine is cold, the hesitation issues are completely gone.. but then when its warm, the issue is back.
ive tried lowering the requested boost to see if it helps, but no go.. so im thinking i have seriously missed something in my fueling.. any ideas or suggestions on this?

i can see the oem fueling is setup in a pretty complicated manner using KFFDLBTS and KFLBTS.. and im thinking i could alter this to suit my needs, but i want to know what im doing..

..do we have any fueling gurus out there to give me a few pointers?
