Wow thanks for dynoing my car. I'm just telling you I raced a 06+ ss impala from a 30 roll and whoever got the jump held that lead till 100. I couldn't pull on him, he couldn't pull on me. That was even with my blower hot and a **** tranny. I know now I'd pull at least a car length on him to 100

Don't worry, that's crank bullsh1t.
LS4 cars struggle to make 260~ FWHP...that's why a stock-ish blower car can hang or beat up on them.
Their drivetrain loss is pretty decent...think close to 20%-ish.
That and their intake side and peanut cam doesn't help anything either.
My car is stock. Stock pulley, stock **** tuning, only performance mod I have is a shift kit if you can even call that a "performance mod" I don't consider exhaust and intake to be a mod cuz they don't add power just "free" it up. I don't think my car makes more than 200hp to the tires if 200.

what kind of tune are you looking to get? If it's just a canned tune you can keep modding with the same pcm. If it's a custom tune throw everything on your car and drive it to the tuner.
usually canned tunes are tuned according to your current mods.
if you drop a pulley after you put a canned tune on, you are going to need a tune.
I'm talking price on additonal canned tunes after I buy my tuned pcm

youd have to talk to your tuner/vendor on that one
That's what I figured

Nope! A PCM will take you through all the basic mods. If you do a cam or have to do injectors, etc you will need a cutom tune. You can drop all the pulleys you want but you'll do a lot better with a custom tune.
I agree with dsmuts on loading up than get a great tune.
