Has anyone noticed a power increase after driving the 6.2 a while? I have test driven several 6.2 F250s, all with 3.73 gears, and with different tire sizes. I'm not going to say the trucks were "weak", just not peppy by any means. I know it may have a decent bit to do with drive by wire as the 5.0 feels very similar in the f150. I have also driven the ecoboost and it doesnt have the lack of response. I have both a 2003 f250 6.0 and a 2009 f250 5.4, both seem to have better pep or throttle response. A 5 star tune is out of question (need that warranty), do the 4.30 gears fix this?
