how much horsepower SHOULD i have?
ive seen all kinds of reviews on the stock 99 vortec 5.3 and it seems like they all say something different. from what you guys know, how much bhp/tq should i have with my current setup?
flowmaster (i assume about +5 to 10 hp)
k&n cold air intake (i assume another +5 to 10 hp)

215HPs to the tires wouldnt be suprised to see 195HPs to the tires since its a 4x4. ive had mine all over dynos and they dont push what the factory says they will and 90% of the time your disapointed.

prob a 30 hps is a safe guess but who knows you might crank out some more.

Yeah - about 20% drivetrain loss plus your mods would put you at about 250.
Yeah, 240-250 does sound logical--since it is a 4WD truck. After LT's, ORY, and tune, you should be looking at 280-290.
