Numbers vary from car to car, Dyno to Dyno, temperatures have an effect as well as altitude. It is a decent average though.

Mine was 379/373 on a dyno jet

That's for sure! there was a 2010 Camaro ss who was next and had the same set-up as mine and he wasn't even close to the numbers I did! even the tune guy couldn't explain it..... I was like that sucks!

It honestly doesn't matter. Dynamometers are a precision tool, not an accuracy tool. Two different dynos can yield very different results. Even the SAME dyno can read huge variances between pulls. I did three pulls on a Dynojet bone stock and they varied 10 rwhp. That's HUGE, especially since a mod like headers are only good for 20-30 rwhp!

Using a dyno is useful for tuning on that exact same dyno under the exact same conditions, and even that is subject to significant variance as I explained above. Truly, the best gauge is the track...but then you take into account the biggest variable of all - human error

All that matters is if you can feel and hear a significant difference. 99.99% of your car's life will be spent off the track and dyno.

These were my three back-to-back-to-back bone stock dyno pulls. These were straight off the interstate, no cool down time at all.



I could easily tell you I took a baseline, then put on a CIA and saw GAINZZZ. NOPE! That's just dyno variance. Remember that next time you see mods claiming gains of 5-10rwhp. They are so easy to fudge it is ridiculous.

So Op, what are all of your mods?

Also, are those the dyno results after a tune?

LTH, Vararam, straight cats, and muffler delete. these are the results after the tune!
