Assuming you're on the stock L99 cam springs and lifters, that would explain your numbers.

Here's mine..

[JEFF75645]

Did 2 pulls on my 2011 L99. Bone Stock.

STD:
1st: 342.31 Hp 339.93 Tq
2nd: 340.46 Hp 331.56 Tq

Cant seem to get the dyno sheet attached.

[Mongoose03]

Very good numbers

[bmbbl be]

here is my latest dyno run ,,,,maggie 3.6 pulley/ cam / headers/ cai/heads ported,,,and this with 22's on the car !!!

582rwhp 522 tq

[Milkman20]

hey do these numbers look correct for my mods?

TSP VVT-3 cam
Ported Stock Heads
Melling HV oil pump
LT headers - no cats
CAI
Stock Torque Converter.......soon to be changed

[Rhino79]

Seems about right to me, tq looks low though

Hey guys, here mine from this afternoon. Temp was 84 and humidity was 14% according to the dyno sheet. Considering all my mods, I don't think it's really anything to get excited about, but oh well I guess I just had higher expectations. Car feels strong when driving though, so I suppose that's what matters.

JANNETTY RACING CUSTOM TUNING on SuperFlow WinDyn V2.3

MAX RWHP: 367.4 MAXTRQ: 375.1 A/F RATIO: 12.5
(i even reached 369.1 rwhp on the screen)

6/8/12 76F 44% HUMIDITY

mods:
AMERICAN RACING HEADERS 1 7/8" Primaries With 3" Merge Collectors, 3" X-Pipe (With Cats) Includes Mufflers With Polished S/S Tips
Cold Air Inductions COLD AIR INTAKE
Apex Motorsports INTAKE SCOOP
VMAX Ported Throttle Body
JANNETTY RACING TUNE


(my previous tune was done on HP Tuner on a DYNOMITE.. although DYNOMITE tends to show higher numbers)

i am so happy with the response of my car now.. THANX TED JANNETTY !!!

i know that ted jannetty did a great job on my tune and i could feel it. but based on my bolt-ons and what their respective companies claim how much hp it gains, my numbers is kinda lower than expected.

each product is claimed to be:
ARH headers, xpipe, cats = 30hp
CAI cold air intake = 15hp

then a tune could pick up around 20hp

with stock L99, its average is 320rwhp + bolt-ons and tune = 385

plus i got intake scoop and vmax tb

but its just numbers and every dyno is different and not accurate

so, who got the same bolt ons as mine and whats ur numbers?

When I was bolt-ons, my numbers were very similar (376/391). It's hard just to add together advertised horsepower (because they never clarify if they mean crank/rear-wheel/or dyno-HP), but in your case, ~370-dyno sounds about right. For example, mine responded so well to the bolt-ons that the tune added only 10hp.

i wasnt thinking about that.. thanx for reminding me about that.. when i recalculated, based on my bolt-ons and tune and 20% drivetrain loss:

ARH LT's, xpipe, cats = 30hp / .20 = 24
CAI intakes = 15hp / .20 = 12
tune = 20hp / .20 = 16
------------------------
total = 52rwhp + 320rwhp stock = 372

so i guess mines is right about there

I posted my graph right above yours. I was expecting higher numbers too, based on all the advertiser's claims. I've heard gears can lower dyno numbers slightly, so that might have something to do with it. Ted tweaked my tune a bit after this, so I may have picked up a few more HP.
