I have a tuned 2014 E63 S-AMG that was a custom tuned and had the mph limiter removed the tune. I dyno on both mustang and dynojet and will say that I cut off the dyno jet at a speed of 200-mph plus...honestly I believe that pull was in 4th gear. I am getting a re-tune with down-pipes and a handheld device to switch between 93 and race gas. I cannot wait to see what the numbers are here, but as they say numbers are numbers until you get to the track!!!
Mods at time of initial tune on Mustang Dyno (7/13/18):
1) Intake spacers with upgrade filters
2) Cold spark plugs
Current Mods (Dynojet 6/03/19):
1) Custom tune
2) Intake spacers with upgrade filters
3) Muffler delete
4) Cold Spark Plugs
Results...Mustang dyno 555 whp; 641-torque 4th gear pull and 567 whp; 708 torque 5th gear pull. Ironically, the results for the dynojet were similar though I was hoping for higher numbers 8% higher on the dynojet. On a side note, the car may have been slightly heat soaked on the Dynojet?!?
Additional upgrades Scheduled in three weeks adding down pipes and upgrade tune to include race gas. I will post the numbers if anyone is interested?!?
