I know that we have sort of been over this before, but what kind of H.P. is everyone getting with what mods and what octane fuel are you doing it with on a 2004+ 5.4???

Thanks in advanced,

Rob MFK.

 

unsure of power/torque numbers. can't wait to get it dyno'ed, maybe this summer. only problem is no base numbers to go by. i run 87 and it's expensive enough. 4.88/us gallon. premium is 5.22/us gallon. 1.29/litre and 1.37/liter respectively. mods are in my sig. have fun.

 

Rob I have a 08 w/5.4 with the x3, custom dyno tune on 93 oct. , with a AF1 3.5" installed and I picked up 44 RWHP. The old SOP meter feels like it's more than that but the Troyer dyno reads low compaired to others.

 

Does anyone in here have a programmer? is it the best bang for my buck?

 

See my siggy, if you click on the link you can see the dyno graph. I have a 5.4L and I only run 93 octane.
