xHP Stage 3.....throttle closing on shifts?


Jul 7, 2020
I'm running a stage3 xHP tune on my 07' 335i. I like the way it shifts, but it still feels like the motor is cutting power a lot as it shifts. I'm assuming it's pulling the timing back and/or closing the throttle body for a spit second as it shifts to put less load on the transmission?

Is there a way to dial some of that out? Would the line pressure bump option help? What about playing around with the Torque Reduction on Upshifts settings?

It just feels like it's giving up a lot of power when it shifts.......

Anyone else have that issue?
