Is this possible?

i attached both the full log a one i cut out everything other than the relevant info.

I am pretty sure your computer's clock is accurate, so the way you calculated your 0-60 should be perfect.  That is what I was doing.  Are you logging to a PC or directly to X4?

Okay, Wallace shows 5.18 0-60 for me and I got 5.51 from my log.  This was my 13.81 @ 98.24mph.  I think the head start you get at the track before you trip the beams makes a big difference.  The log will show longer to your trap speed than your slip as well.  Just going from a shallow stage to a deep stage is worth over a tenth in the 60ft.

Brucelinc's mks did 3.9s all day, based on the Aeroforce gauge.

As does my MKS (same year and tune as Bruce).  3.94 actually per my Aeroforce.  3.92 per my G-Tech.   No mods other than "4X Plus" 3 Bar tune with the soft 1-2 shift modification.

The only issue using Aeroforce for times, is that if there any tire spin, that comes into play.  I did couple passes at the track usinh mine.  It was showing times, before I crossed the end of the traps.  Was about tenth or better off.

Something to keep in mind is LMS does boost mapping.  They are *likely* playing with the wastegate to keep pressures higher than normal... and they also can control a great deal of the shifting behaviors versus SCT's limited interaction with the PTU's.  this can account for quite a bit of gained time 1/4 mile in the 1st half of the track...

After that 1/8th things normalize out from a number of youtube vids and then 'same/similar power' but lighter sports cars start pulling us in,  on a 1/2 mile track we'd lose a bit more than we currently win with regard to SHO vs stock v8 2015+ stangs and very similar sport car weight/power profiles.

What do you mean interaction with the ptu? The ptu is strictly mechanical isn't it?

What is boost mapping?..i think you may be over thinking it topher

correct. there arent any clutches in the PTU, the clutches are rearward of the driveshaft before the RDU. the PTU and driveshaft are spinning while driving at all times.

Livernois is able to do more with the Torque Management, if that is what you are referring too.
