Ok, Checked my fuel temps towing w/ my old edge tuner. I saw 210 once on a steep incline that makes about any loaded semi grunt. Maintained 55 the whole 60 mile trip with ease but outside temps were only 90 tops. My fuel temps hovered 170-190 most the time, when I hit over 210 I was pushing it and hit 65 MPH by the top. I did get p0087 on that run.
Do I need the extra cooler?
