Went To OCD customs

I just want to share with you guys my Dyno numbers, I know its in std smoothing correction and all Dynos are different. With that said the guys at OCD customs are outstanding and very helpful , highly recommended. We did about 14 pulls with some down time to kool off. They custom tuned it to until it was consistent at around 400 rwh. All i have is a muffler delete, K&N Aircharger and the predator custom tune by OCD. I can definatly feel a difference ( Butt Dyno)

Side note: First(Base) run was done w/ Muffler delete and K&N aircharger no tune and second one on graph was the last pull

Nice dyno BUTT.....thats STD and Smoothing 5 to boot! . Engines are rated by the factory SAE. If you have that chart corrected to SAE which is the correct way your gains were significantly less.

This is from a magazine article on "dynojet" dynos.

SAE j1349 correction:
29.23 in/hg.
77 degree temp
0 percent humidity

Standard correction:
29.92 in/hg.
68 degree temp
0 percent humidity

What this all means is that "Standard" will give you 2.6 percent better numbers (very popular for the import crowd). The example the magazine gave was a Vette making 412 (SAE corrected hp). With the Standard correction it made 423. All that you will have to do is multiply your "Standard rwhp" by .974 This should equal SAE (the one everyone uses).

Also if the dyno is not maintained or calibrated or if it is not "loaded" which it most likely was not you may have lost horsepower/torque. Best way to see if the part works is to run her down to the track for comparison.

Good Luck!
