Final Numbers- UpRev Osiris Tuned
I got the car tuned 2 months and a half ago and was very pleased with the results.
All of my dyno's have been performed at Church Automotive on the same exact dyno machine. From stock baseline, to NA, to full bolt-on + tune. And yes, Church's dyno reads high in comparison to others. But its not the numbers itself I care about...its the gains.
First, here's my stock baseline dyno (notice how consistent dynapacks are ):
This second dyno compares my stock baseline against my car with an intake, exhaust, test pipes, and 5/16 MD spacer:
This following dyno compares my car with an intake, exhaust, test pipes, and 5/16 MD spacer against the same mods + the MREV2. But, notice how may car LOST power. The car was pinging pretty bad and it is evident where since the ECU pulled a bit of timing atleast in 3 areas under the curve (hence, the power loss). This particular dyno was conducted during a dyno day and a good amount of cars were experiencing the same issue. Winter gas blends?
Now, for the tuned results. Shawn at Church Automotive was offering a great offer for the Osiris tune during the dyno day. I couldn't pass the offer so I purchased it and the car was tuned a few days after the dyno day. The car still had the same gas that was used during the dyno day (dyno where I lost power due to knocking). Overall, I was pleased with the results. The gains throughout the powerband are great. And Shawn managed to play around with the exhaust timing (a revup feature) and, as you can see, my car doesn't really lose much power after peak power (another characteristic of revups). This graph compares the previous full bolt-on dyno (knocking issues) against my final tuned results:
And now, here's a graph comparing the stock baseline against my tuned, full bolt-on 6MT Coupe:
Much thanks to Shawn @ Church Automotive. I love the great torque gains for daily driving and love the fact that I gained power throughout the whole powerband. An UpRev Osiris tune is a must for anyone looking to squeeze out the most out of their NA project

Good job, all the way around. THIS is how a car should be modded. You did it in sequential order, with same-dyno testing, and graph overlays to be able to compare total gains across the rpm range.
And what you got was consistent 20-25 WHP and T widely across the board... great results for NA. There is a little fall-off above 6K rpom that I would look into, but might just be the spacer/mrev tradeoff... but other than that, very usable gains of +10% from minimal bolt-ons and tune...

Yep, the torque is great for daily driving. I honestly hardly ever have to downshift to pass cars unless I have the need for speed

I don't see an issue with the power drop off. I've seen a great amount of VQ35DE dyno's, non revups and revups, and this seems to be normal (though the power drop off is a little more dramatic on the non revup).
My car was still making 274 hp at 7100 RPM. That is only a 12 hp drop off from peak power @ 6150 RPM

I'm sure your top-end is more impressive than mine (thanks to your more aggresive aftermarket cams). The average hp throughout the gears (in most cases ~5000-7000 RPM's) is what would matter most in a drag run, aside from the initial launch itself.
Thanks to the torque numbers, the car itself has a great powerband. I really need to drive a stock G35 to appreciate it even more

I don't think I can take you at the track. Do you happen to have the dyno files of your runs? I would love to overlay mine with yours.

Don’t under-estimate that torque... I'd take that torque over hp any day

As far as the torque, well, the more torque, the more hp (as seen on my dyno's). Torque really affects how the powerband will shape out to be. But during a drag race, you would be in the high RPM's for most of the time. I'm glad my gains where great all around the powerband.
I am definitely not underestimating it...im enjoying it

The torque is actually very smooth. It's just the way the dyno is plotted (I can change the axis on the dynapack viewer if I wished, but I leave it at autoplot). If I "zoom" away from graph, it would appear alot flatter.

You should get all your dyno files from Shawn and use the dynapack viewer. It's awesome

I've raced cars with higher peak hp (but much lower mean avg trq) and beat 'em. Your peak hp isnt what I'd be affraid of in a race with you - but your mean avg scurs me
