The oscillation distorts it a bit and maybe it should be around 360whp but very impressive nontheless...However, Stage 2 with mods and 93 oct might get close to 400whp it seems!

Great results and congratulations!!!

Looking forward to your detailed review.

P.S.

If you got the actual dyno files, please post against JB3 with mods and 91 octane.

Thanks again!

So what was the correction factor number?

Interesting! Not a knock out punch but enough to keep my interest.

Compared to the JB3 map 3 power and torque seems very similar. Which V3 map would this be equivalent to, Stage 1? How would this compare to JB3 map 7 and V3 Stage 3 on 93 octane?

Also this test was done with the hood down and stock airbox like last time right?

I really wanted to do a complete write up but I don't have time so I'll just post the runs now.
The oscilations up top are because this flash is developed to be driven in the real world and not for a dynojet.
This is the reason why there is no oscilations on a mustang since there is a load that is simulating street driving.
Enjoy.
Looks great and very similar to your last round of JB3 1.22 map 3 runs!

Not bad power for those boost levels but I still don't see why everyone is going ape shit over this flash.

Needs 93 oct with more boost in Stage 2 to really know for sure. Also, a graph overlay of both might show us a bit more. The GIAC looks like it keeps a lot of the power toward the redline (after peak power).

Thats probably because they have full timing control . Holding the power almost to redline and the flat torque curve is really the strenght of this flash.

I don't think timing control has anything to do with the power up top. They are simply runing their peak boost longer.

Is this with the DCI or Drop-In? If it's with the Drop-In, he is making as much power as his JB3 1.23 Map 3 with a DCI..at peak. If not, it's about the same but seemingly smoother, outside of that oscillation.

I don't think so.
Below is when I dyno'd with map 4 at the dyno day at MD Automotive. At this time I was running JB3 1.3 map 4 (Run 79).

True. I wasn't using the dyno glory DCIs.

Agreed, much different curves. If you are comparing dyno's I would say that is damn close to a knock out punch, and this is the reason people are going ape sh** over this and for 4 main reasons I see here.

1. More power under the curve, it holds very close to redline
2. More TQ under the curve
3. Less Boost
4. Much safer AFR, GIAC is nice and fat, the JB3 is lean IMHO

Of course what really matters is side by side comparo's, hope to see those soon.

Looks like it, but keep in mind JB3 map 3 is the most conservative map with respect top end boost decay. Also he is running 1.22 software, which had even more top end decay than 1.3 and 1.4 beta variants.

I guess you do so many dyno runs I don't remember all of them! For example I remember at one point you made 390ish on 91 octane with JB3 1.0? And I remembered those runs last week @ 360-370ish with the hood closed on map 3.

Anyway you can see at higher RPM where you're making more power you're holding more boost. Map 3 is setup to be more conservative up top, and map 7 for example to be much more aggressive. The reasoning is to keep the turbine impeller speed down on the lower maps for those that want to be more conservative.

Mike are there any dyno's of the JB3 or Procede that you know of that hold power to redline like that? That run at those AFR's? I haven't seen most of the dyno's posted on JB3 or Procede, but out of the one's I remember the none flash tunes drop off well before redline, if there is dyno's my bad!

I'm curious, what makes you say that? I haven't been aware of any n54 tuners with detonating tunes. Then again, I haven't been reading this forum more than a few weeks.

It seems there are an awful lot of juicebox people out there using them without much issue. But maybe they're not pushing their cars to the limits?

AFR on the GIAC runs are in the high 11's, the JB3 runs are near 13 up top, on a FI motor at 13+psi not sure that's the best place to be mixture wise, detonation is not always audible BTW.

Having said that sniffer readings on dyno's are not always accurate, a wideband , with an afr gauge, would be the best way to see where you are at and you are right there are a lot of JB3 owners out there running strong.

You're talking about a couple different things so I'll bring them up for you.

1st off, I did make around 390ish whp with no lid on the airbox, so with no filter. Another thing...I did make that power but what happened? Where did that map go?
I'll put it on a comparison for you.
I'll also add the run with the lid on.
Here you go.

2nd will come in another post.

I don't know if there were map switching back then.
It was the first of the JB3 maps.

I'm also going to close this thread since the other one is started.
