I have a 2012 F-150 Ecoboost 3.5L, I think I'm going to add a catch can.
I replaced the spark plugs today so I could run a 93 Octane tune to add 90hp
!! They looked pretty dirty. I'll report back when I fill up the tank with 93 & install the supertune.
I put the 87 octane tune on already & can feel the 50hp it added. Now don't get all excited this is on the larger V6 3.5L ecoboost, so the Pony car's ecoboost won't get that much with a tune only. :/
