Hey guys,
Bought my fiesta st12 days ago with half tank of 87. Ran it to 35 miles to E then 93'd it up. I've got my cobb tuner and I want to load my 93 map and run it hard (Just got the tuner today). So I'm currently 22 miles till E and I'm going to try to run it down to 5-7 miles to E and then fill it completely full with 93. Do you think I'll be safe and won't face pre detonation?
Heres the specs :
Half Tank of 87, ran down to 40 miles
Filled with 93, ran down to 5-7 miles
Filling with 93 full.
Do you think I'll be good, or should I run with the 91 map for a week and kill another tank?
