I have a 6000 lbs avalanche with a LQ-9 with dynatech long tubes and high flow catted y pipe, trick flow UD pully, flexalite 282 twin monster fans, K&N intake, BBK 80 mm TB , Gibson cat back dual, 160 stat , FLT 4L65 LVL 5 with a yank 2600 stall, 410 gears W/ a eaton posi,and a Nelson tune. I never got it to a dyno so I was wondering if any one with a similar set up or if someone has a good geuss on what #' I might be making so I'm not surprised when I can find a dyno to check. Also i still have the stock injectors that came with the LQ-9 do you think I'm losing anything from having the stock ones or could I gain anything from bigger injectors?

What size tire? That will make a difference at the dyno too.

Don't be shocked when it seems low. My 5.3 with mods close to yours made 236hp/284tq. So figure whatever the extra power the 6L gives and add it on. I'm gonna guess under 300.

Smaller/lighter tires will show better numbers on the dyno.

Larger injectors have no performance value. They just provide more fuel when you build your engine past the point the stock injectors can support. A 250hp truck can swap to 96 pound injectors (and tune for them) and it's still gonna have 250hp.
