    just curious if you knew the rwhp of an 06' 4.8l with the 5 speed manual, and what kind of gains have you seen with that combo from tuning? all stock of course.

    id say go with a CAI and pacesetters with 3" y pipe thatll give you roughly 20hp and then id go with an aero or magnaflow muffler they have good sound and arent too loud at idle plus with the CAI and longtubes you can run a more aggressive tune

    haha come on G we all know you are deaf already and you prolly forgot to reinstall the magnaflow after the complete rebuild of your truck. You are getting a little forgetful in your old ginger ways.

    on a standard, i'd say another 10-15% more to the wheels.

    i remember a 4.8L, 5speed on the dyno last year, small cam, shorties, 100shot, laid down 448hp to the wheels, on my greedy dyno, that's good.

    allen- seen your post on that nice chevy!
    just a quick question, based on that short bed, what do you think that truck will do in the 1/4 mile, thinking it has stock gears ( 3.42? ) and no possi rear, so based on that, what would your figures be or about?

    and second- if that same truck with the mods you have done to it, plus adding a ram air sys, will say a k & n filter, and a higher axle of a 373, not a 4:10, because it will travel alot on roads, and lets say a delete cat, what estimate will you configure with those other minor mods done on that same truck?
    thanks allen, and again, nice job!
