enoel, does SSi have a race tune as well?Our Da on this run was 2700+with 97% humidity..87°.. Shifts we're very firm..I think I lost a tenth in the first 60' spinning through it!..lol..Which would translate to 2-3 tenths on the big end..Would love to see the 12.54 timeslip..If nothing else just to compare 60'-330'-1/8+mph..
Of course if all you're looking for is the fasted sedan stock in the 1/4 mile, I suspect that's still the Tesla 100 in Ludicrous mode at 10.52 seconds.what was the 60 ft on that run - with that high of a trap it must have been over 2 - Our best trap is 107.4 but we did not have our best ET due to a 60 foot of 2.05 - Best run was 60 FT of 1.84 - with DA of 346 ET 12.54 Trap 105.7 - but if you ran in Dallas area I am sure the DA was not great and that is nice to see --it seemed to maintain power thru the run - and that has been our issue running in heat and humidity here in NE - good 60ft pretty good 1/8 and then it goes to crap on the back end.
Side note - saw one of the fastest STOCK sedans - 2017 BMW M5 - ET 11.29 Trap 132.8 Kicked a Hellcats Butt
While more power = more stress, the HP difference between an LMS or Unleashed tune to this wouldnt be enough to cause any sort of concern. For me when I saw this thread I wondered (silently) if they were pushing the tune too far. Tuning a motor is a balancing act, getting the right AF, Timing, Temperatures takes a lot of work. Ford would give this car a very conservative tune, designed to make the motor last longer and meet emissions. Most after market tunes try to keep the engine reliable while taking away the emissions and upping some of the power Ford left on the table. LMS and Unleashed tend to run very similar times and both are very reputable tuners, I would imagine they came to very similar tunes by just following some common sense regarding safe tuning practices. To see such a drastic Trap speed increase would indicate a drastic HP increase, something that I feel in order to achieve would mean pushing the car to levels LMS/Unleashed are not comfortable doing for a reason. The harder you push a tune without proper supporting mods, the higher the risk for engine damage becomes.
