I recently installed a '13 TVS on my 2011. I added '13-'14 injectors, VMP 67mm TB, and KB dual BAP. Lund is doing my tuning remotely. The car pulls like gang busters under WOT and drivability seems good. The issue I am having is under part throttle ( roughly 40%-60%) the car bogs for a second or two, boost starts fluctuating dramatically, the rpms start to climb slowly while the boost is fluctuating and when the rpms finally gets high enough the boost kicks in and off I go. This is all while holding the throttle at the same position. It does this in every gear but seems the worst in the higher gears.
I swapped out the boost control valve that came on the TVS with my stock one and that didn't help. I also put my stock TB on and that didn't help either. I have checked for vacuum leaks and don't see any, again car idles and drives fine. Lund has looked at my datalogs and says everything looks good.
Has anyone else experienced this problem and if so what was the issue?
Thx
