throttle seems very choppy. feels very on or off. when i get low on the throttle at slower speeds its quite choppy.

here is my setup at the moment:

2008 SD 990 USA
Leo Vince slipon
motohooligan airbox
SAS removed
MAP: 07-08_US_SD_Akra_Map_smoothened.hex

besides the choppy throttle, bike seems like its choking on too much air when i WOT below 6k rpm. Choking on air is just what it sounds like is happening, bike kind of lags and does not get into the power until after 6k rpm.

Can someone please help?
maybe a remap is needed?

TPS.

What's that mean?

Throttle Position Sensor.
