That is normal at powertech, their tail pipe sniffer reads about 1 point leaner, thats pretty common for most tail pipe sniffers. 11.8 for your car is normal.Just a note ... They used a new 02 sensor but it shows 12.8 while my AFR gauge on the dash was reading 11.8 ... Every pull it was a full point different between the two readings .. They also printed it out in the MPH scale , I should have had them print it out in the RPM scale ..Doesn't really matter seeing I was just looking for peak numbers anyway .. It just makes the chart look funny printed in MPH mode ..On my bike dyno I always do RPM scale ..
They had done one other 2015 Mustang back in 3/15 and it was done in 5th gear , it made 432 HP .. So I checked the data on that run and it was 73 Deg and low humidity .. My run as you can see was in the mid 90s and higher Humidity ..
