hemipowerv8 will become famous soon enough

Most tuners include the speedo recalibration if you ever plan to do that...
The difference is about the same as the tires...35s over 33s is about 6% difference and that's about the same as the speedo errors above.
Thanks for doing that though! Very nice info.

This same 6% gain, makes your MPG about 13.7 mpg instead of the indicated 12.9 in the photos. Not bad for big 35" mud tires and a HEMI! Wonder how much the Magnaflow and S&B help that out...ordering both for my truck (14" and Y from Mf and the oiled filter CAI setup from S&B) asap!
Mods: Tint, Line-X spray in, PD emblems, Weathertech mats, Honeycomb grille, Mopar tow hooks, Magnaflow 18" and Y, Bilstein 5100s @ 2.1" & TGC rear spacer .75", Toyo All terrains 35x12.50x20, 5" black tips, BakFlip tonneau cover, 87mm tb
Next: Gorilla lifetime lug nuts, CAI, Diablo tune.
