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)
250ish range....if you really want to know go to the events and gatherings forum....we are having a dyno day on April 5th....come on out
about 250 hpQuote:

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.
what do you guys think ill end up with when i get my longtubes/full exhaust and tune?
.......... its a 99 had like 280-85 brand new is that flywheel numbers virgil or rwhpQuote:

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.
make sure to let us know if you get it dynoed id like to know how close i am.
