I'm Awesome
I had a first gen Titan that was like that too. Intake/Exhaust/Tune had it at just shy of 300 RWHP @ 4,900 rpm and 400 rwtq @ 2,900 on a Mustang dyno. With the factory tow package 3.36 gear it was suprisingly good on gas towing. I would lock out 5th gear and use the Tow Mode. That engine would just sit at 2,500 rpm uphill at 70 mph. I had over 8,500 lbs behind it multiple times and could not have asked for more grunt. I averaged 15 pulling the G-van on the trailer.I got about 16-17 out of my ecoboost couple weeks ago pulling a Bonneville up and down hills maintaning 65-70 mph. I don't know how much weight total i was towing but i know it pulled it like it wasn't there.
