***Title is supposed to read "Dyno Tuned LS3 w/ Headers IMPRESSIVE NUMBERS?" if a moderator can fix the title i would appreciate it!!!!***
Just got back from Long Beach CA, had the car tuned by Sean in Church Automotive Testing. The Dyno used was "Dynapack Chassis Dynamometer"
The car has Longtube headers by texas speed, no cats and no muffler slp exhaust. Stock air intake box with K&N air filter (has like 5k miles on it and i forgot to clean it before taking it)
I wish i would have run the car on the dyno before the headers to see what it would be like from full stock to headers and tune.
The numbers you'll see will be from headers and stock tune... then headers with tune.
According to the tuner he says a stock one would have been around 375hp and 370 torque on the dyno.
These are my numbers:
404.96 HP no tune run
412.90 Torque no tune rune
430.90 HP with tune
442.27 Torque with tune
How do these numbers look to you guys? i know this dyno (from what it looks like) will show higher number then a Dynojet but according to the tuner, the dyno they use is more consistent. The only difference i see is there is no weight of the rear tires and no traction to worry about. The car is not lifted, just hanging on the hubs of the dyno. it was lifted from the rear crossmember to remove the wheels.

Nice results, they do seem a bit higher than normal but clearly good results nonetheless. Now you have a good start to go from when you do more changes.
The numbers may be a little high but it appears from the data you posted that they gave you uncorrected numbers. The weather data in Long Beach suggests that the DA was about ~1200ft lower than the SAE standard at the time of your run and the TCF (correction factor) value on the graph you provided is 1.000. Meaning that there is no correction factor adjustment. It would be in the ~420 range with SAE correction which is right in line with a full tune, no cats and long tubes on a LS3.

Nice power!!!!
thanks for mentioning that! I totally forgot about SAE correction!
I just posted above my results from Kook's long tube headers and Corsa intake...went from 385/380 to 423/420 on a dynojet. 38 hp gain. The sound is AWESOME!
