Yeah I'd guess your tire size is off if you measured it. the programed tire size is typically about an inch shorter than the advertised tire size.
Thats where a GPS or gps app comes in handy so you can get the speedo to read 60 mph when the gps also says 60 mph.
If not with a 5.2 0-60 mph (if you weren't spinning) my initial guess would be that you would be running an 8.5-8.7 sec 1/8 mile at 75-78 mph on a track
Not impossible but it does seem a bit quick on average for your mods
Have you ever run it on a track?
Take a look at his profile page. He posted images of the tire size measured. And its right. Its just hard believe. If everything is right, which after talking to him it sounds like it is, its just a pretty damn quick truck for the mods he listed.
