I think it may depend on if it's the 28 or 35. For me, I thought the 28 had more of a noticeable lag before the RPM changed but the two engines are basically the same (n20 is a n55 with 2 cylinders removed) so I'm wanting to lean towards the ZF 8HP transmission (which is also just a modified ZF 6HP with support for auto start/stop and 2 more gears) being the reason there is more of a pause on the 28 but I have no real data to back that up.
