My friend has an 08' 4door powerstroke and he just added an afe stage 2 intake and edge attitude module. It has a feature that records quarter mile times. With the intake, and chip on stock setting it ran a 16.4, then on extreme mode which is +100hp in 4wd it only ran a 15.6. Any ideas as 2 why it is this slow ir is it normal? We were both hoping for around a 14.9. Would customizing the settings insted of going with the extreme tune settings help? Any help is appreciated
The transmission also seemed to slip alot on the extreme setting, any cheap upgrades to help with this??
