    TSP 220 in 4.8

    Just in case you're wondering what a TSP 220/581/112 sounds like in a 4.8 here you go.
    I got an idle vid of my truck. Exhaust setup is LTs and 22" big body magnaflow dumped before the axle.

    Then i took sum pics. Notice anything different? When I got the truck in 07 it was a W/T package. That means black bumper and grille, manual windows, locks and mirrors. Hell it didnt even come with a CD player. In 08 some idiot backed into my front end and thats when I replaced the front cover. The grill is the factory black one thats been sanded prepped and painted. Had the rear bumper caps painted about 8 months ago and I think it looks killer.


    Just washed her

    Yup dropped it 5/7 on accident. Then I raised it to 4/7 because my front springs are sagging about an inch. Ive had the cam in it for a while and ran good but only 15.1 at 93 mph with 3.23. Got 4.10 and locker installed about 2 months ago and in 2 weeks were gonna see whos truck is faster. My brothers 2010 5.3 T70 @ 11psi or my 07 4.8 cam, stall, headders and gears shiftin at who only Allen knows what rpm. 6200+ I think.
