Upgrades equal less power?

Ok, so then what would be the RWHP of a stock LQ9, 290 to 300? What kind of horsepower did each mod contribute, if any?
I raced with a guy last year whose only mods are longtube headers and a local tune and he made 320 RWHP with his 5.3 PPV Tahoe. My 5.3 only has a BB tune and makes 300 RWHP. These are both Gen IV motors.
Next time out I'll run a new baseline since I've replaced my Y-pipe and cats. Then will make some runs comparing the stock paper air filter to a K&N. I might buy an Airaid Jr and try it out on another visit to the track. This mod also allows a baseline to be run the same night unlike mods such as a torque converter or camshaft. Of course I'll also have to decide whether or not to continue with 2WD launches or launch in 4WD from now on too. Whichever course is taken, it should be stuck with.

So which cam do actually have??? you said stage 1, but listed stage 2 specs???
If you still have the 3200 stall, why not swap it out.
Tick Performance "SNS" torqueMAX Stage 1 Camshaft for LS1 & LS6 Engines
223/227 | .610"/.590" | LSA111+2
Tick Performance "SNS" torqueMAX Stage 2 Camshaft for LS1 & LS6 Engines
Standard Lobes: 227/235 | .618"/.605" | LSA110+3

Stage II is what i have. Its for the ls1 not the bigger ls2 version is what i should have said. I think i should try going back to me 3200 stall and 3" single exhaust to try to gain back some lower end power. The more i drive it the more she feels stronger up stairs. With the combination of going with a bigger cam, lower stall, bigger exhaust then adding the 6 gear planetary which raises the 1st gear ratio . I really hurt the lower end torque.

Any updates on this? Curious to see how it does with 1 3/4 and single 3" exhaust. My 06 single cab with 5.3/60e has 1 7/8 long tubes and dual 3" all Speed Engineering. Runs decent

Need some compression to go with that big cam too. You may not have lost any power up top. In fact you likely gained. But a big cam cam rob power down low. You need some 243 heads to up the compression. The 243 heads were a great mod for my big heavy truck. The seat of the pants dyno told me I picked up quite a bit of torque. The real dyno backed that up. I made more torque than horse power on the dyno.
