Ive got a 04 lb7 with 4inch exh, intake, ppe boost valve, and edge juice with attitude, usually set on level 3 or 4.

What kinda dyno numbers are people seeing with this sorta combo?

is your truck automatic and if yes do you have any slipping problem cause i have been reading on this forum that allison can't really take more then an extra 90 hp or so .i just bought and 04 lb7 automatic myself and was wondering if i was gonna go with a programmer dont spend money in my tranny right now but defenetely want to go with exhaust and cold air

350hp plus or minus 10 or so, to the wheels maybe, thtd b my guess on level 4...hard to say

and no problem with your tranny yet

I would just get the exhaust, not the cold air intake. Do the Kennedy Airbox mod instead.

whats the kenndy airbox mod? link?

thanks

You might check out the fuel system/ air mod posts and read the sticky aftermarket air mods/filters do they work. To keep it short it said that air filter/cold air systems add no power to a turbo diesel. I had seen something like this in a truck magazine that explained that the turbo sucks in so much air that their is no gain in power over stock in the aftermarket air systems and that some cheap aftermarket air cleaners ran a risk of getting sucked in the turbo and engine doing dammage. This I know will get alot of the guys who have spent money on the air kits ticked off but read the sticky and go from there.

I'd have to dig through my old dyno plot, but if memory serves around 340RWHP with the older ones. Not sure what the latest ones do, but I heard they were a little softer. Be sure to watch out for your transmission and DON'T expect the slip protect to protect you.
