Check this out... I'm gonna leave this lay after this because I feel like I'm beating a dead horse. And like I said before, it really don't truely matter , I'm sure TsT got a good tune anyway.
Stock focus ST with stage 1 on 91oct fuel. At the so. Cal location
This is a stage2 focus ST on 93 oct. It has a cold air intake, FMIC, catback at a location that is NOT at the so cal location.
Am I to conclude that all those mods and a more aggressive tune on better fuel only adds 9whp and loses 9tq ?
Keep in mind this is a focus ST. They see really awesome gains from FMIc normally .
Also... If you look at the 2nd picture. It shows the difference they saw on a focus ST from going from 93oct to E30 ( which is BETTER THAN 100oct ). They gained 10whp and 14lbs of torque ON A FOCUS ST. But on a fiesta ST that WAS ALL READY PRO-TUNED TO 217whp, it gained 23whp on an already maxed out car by adding 100oct fuel ( which again, is not as good as E30 ).
Draw your own conclusions.
