No lag here

2008 Ford F-250 Super Duty Lariat 4dr SuperCab 4WD LB (5.4L 8cyl 6M)
I traded up after my 2006 deisel was totaled. If I had only known I would have gotten one sooner! No noticeable turbo lag with new set up. Interior is much nicer although upfitter switches get in the way of cup holders.
New engine/turbo set up, no noticeable lag
Relocate upfitter switches, and valance under front bumper is too tall. Will easily get damaged off road or in heavy snow
