Modded ls3 owners step in...
If ya don't mind, could you please list your mods and hp/tq numbers, and even et's if you have them. I am getting together ideas for my next car. After owning a heavily modded c5Z for awhile, I think I want some open air driving and am looking at GS's. I really do like the ls7, and the potential it has, my dad has a nice c6Z, but my wife and I at least want a coupe, if not a vert.
Starting mods would be headers, cam (fi friendly) etc, then eventually an Ecs of a&a kit.
So, lemme know what you guys have so I can get an idea on what it takes to reach my goals. Thanks!!

That's inspiring!! Hope to eventually go FI and and be in the ~650whp range for a weekend warrior, but it won't be cheap!With those numbers, you should get a plate that says devil inside!!

Modified LS3
LS3 with 41K miles. Long story short:
Hiway workers left busted up concrete piled up on the side of the interstate. 18 wheeler ran through it with me behind him
. I had nowhere to go but to dive thru the equivilent of a concrete "hail storm"
. Plenty of insurance help bought new GS wide body, ZR1 rims and brakes with huge pilots all around
. I figured: "what the heck"
. What started out as an intake, header and tune ended up e-force 1591 with 3" pulley, Fast 65lb. injectors, Kenne Bell Boosta pump with Racetronix fuel pump harness, Custom grind blower cam (Comp cams), ported and polished heads (new Comp cams lifters, rocker arms, magnum 7.400" hardened pushrods, and Lunati Gold dual valve springs, .660" lift), ARLT coated headers, high flow cated H-pipe, stock NPPs with MtoW switch, Tuned to perfection by Brian Reckert (RPTAustin)
.===651 RWHP and 625 RWT
. Getting 16mpg (ave) on 93 octane and having the time of my life (even when NOT in boost [8.6 psi])
BUT its not cheap
and is addicting If I had it all to do over, I WOULD NOT CHANGE A THING!!!!I LOVE MY CAR!!!

Don't know or care about dyno numbers. They are meaningless if you can't put it on the pavement.
10.82 ET 126 MPH with stock IM and full Z06 exhaust system. Expecting better with the Ported IM and headers.
