C5 of Year Finalist (appearance mods) 2019
my 98 6spd has a k&n cai and b&b bullets it dynode 321 rwhp without a tune. with a 6 spd you typically lose 10% from the engine to the wheels I have seen a lot of stock c5's go over 300 to the wheels seen a stock 02 z06 this past Saturday with 21000 miles go 389 at the wheels so it is possible

... No surprise that I'm still enjoying the stock power these things have. Fastest car I've ever had so far. Definitely fun to drive and admire. I'm sure after a year maybe I'll be itching for more horses

Some easy suggestions... After things like Fluid flushes, Plugs (OEM), Wires (GM Performance "GMPP"), Tires. Here are a few things i would suggest
Cold Air intake:
* Haltech, Callaway Honker, Blackwing (open Filter)
Intake Manifold (IF older the 2001)
* 2001+ LS1/LS6 intake manifold (as Bill suggested)will gain power and easy to install.
Exhaust:
* 01-04 Z06 Mufflers (good deep sound, support 400+hp but quieter for Convertable)
* Corsa (your choice on what style.. smooth can clean)
* C6Z06 LS7 exhaust manifolds... (20-25hp gain on my 04Z06) can be found for $350'ish +gaskets online.
Tune:
* ECS Mail order or Chuck COW
* Custom Tune after parts install (~$450 average cost with dyno, If you wanna come up to Denver I would suggest Clint at American Intense Racing "AIR")

I dont doubt he saw a dyno showing thoes numbers, I would say that the opperator has it setup to be Very generous. Stock 02-04 Z06's will put down 355-365 if the correction factors are setup correctly. My 04Z with LS7 exhaust, CAI and a tune did 383whp 358wtq. now it might read slightly higher on a hub dyno rather then a roller dyno (no slipage). its easy to manipulate the numbers.. important thing is what gains are made with mods on the same dyno.

I've got some ideas for you.....
Well,,,, Having been introduced to C5 from early 98,,, Here are some SEASONED recommendations:
VARARAM VB2 is excellent!
Most any Long Tube SS Header, CATTED Midpipe and NON DRONING exhaust will make you happy
If you have a 97-2000,, A 2001+ intake manifold will add 5- 7 HP.
EXPENSIVE Plug Wires and PLUGS WILL NOT add additional HP/Tq!!!!!! PERIOD!
GM Performance Red Wires is about as good as it gets! Excellent quality wires at a good price.
Our LS Engines DO NOT USE CHIPS~~~
SNAKE OIL!!!!
Headers and the VARARAM are the best bet!
Get all your up-grades and have your car professionally TUNED!

VARARAM B2, 160 stat, American Racing Headers (get the cats), BORLA STINGERS!!!
And don't forget the Chuck CoW TUNE!
Do we know if this is an Auto or Stick car?

No way! A dyno is a measuring tool and I've seen numbers all over the place. I've seen 280rwhp to 350 rwhp on stock LS1 Corvettes. Crazy
Too many variables.. Yes it depends on the dyno and how the tech has correction factors put in.. Uncorrected numbers are going to show different numbers than corrected numbers, depending on the Density Altitude, and temps, the numbers can have quite a large variance.... So yes, 389 rwhp is believable on a skewed dyno(uncorrected numbers on a cold day ), on a stock 02 Z06.. Does the engine really make 389rwhp? No way!

You're right. Too many people get lost in DYNO numbers....That are usually WRONG.
It has it's place and YES I use one..... But not for everything.
As long as you use it for information... (or traction) it's a useful tool.

My first Vette was a 2003 manual tranny Z51 Coupe.
My mods were a K&N CAI and Corsa Touring axle-back exhaust.
It was dyno-tuned to 321 RWHP. I don't recall the torque spec.
The car was a hoot to drive and got 28 mpg on the interstate.
