My times with MaptunerX on my F3 2017 third gear from 60 to 140 km / h (37 - 87 mph). Stock Retracted stage 1. Stage 2 (K & N, Straight Shot ESD) not yet retracted.

First measurement
Default: 7:01 seconds
Stage 1: 6:22 seconds
Stage 2: 6:13 seconds

Second measurement (slightly uphill)
Default: 7:07 seconds
Stage 1: 7:04 seconds
Stage 2: 6:20 seconds

80 - 120 km / h (50 to 75 mph) in seconds with a flying start

Default: 03:25
Stage 2: 02:29
What method of clocking are you using? This would be pretty hard to be accurate without an accelerator of some kind to do the measurements.
