03 Tahoe, 4.8. getting long tubes now. Want to lope. Don't want a new converter but fine with getting new springs. Pretty simple I hope but need suggestions on the cam and a good tuner for all of this. TIA

If you like the hot cam ........take a look at the WS6 store version High Lift Hot Cam

While this IS an excellent cam, I'm not sure a 4.8 needs all that lift (.600+/-) .525 (Hot Cam lift specs)is plenty for that size a motor.
