What made you go with a drop in filter since you had a BMS intake?

I might go on a dyno if I knew where I can find the same dyno as you here in Québec to compare the MP tune vs the jb4! It could be interesting!

Baseline numbers, as in stock hp/tq numbers from the dyno before the tune.

Many dynos differ in readings, so always best to do a dyno run when the vehicle is stock to really see what gains the tune/mods gave.

Either way, impressive numbers considering Mustang dynos usually read low.

The old stock intake box vs CAI argument. More torque.

Oh, yeah, I don't have these numbers. I couldn't get 2 dyno sessions and the DP put on in the same day.

I've heard that Mustang Dynos are for "real world" numbers and DynoJet is just for the bragging on the forums. I'm not for or against either, just glad to get on one.

I'm pretty blown away on the WTQ, all-though I wish the WHP were higher. It may have increased since Mission Performance has reduced boost after 5200 RPM. The hope is to pull timing in order to increase WHP by making sure the limiters on the transmission don't shut down torque as a failsafe.

So popping over to the F30 side another tuner just released a flash and they speak of having the ability to adjust the 8sp torque limiter here soon. I suspect MP will have that here too maybe?

Our specific trans (8hp50) is meant for 500Nm max. Doesn't mean it can't go higher safely.

I was told that MP is going to have a flash soon.

What company has the new flash?

JRAuto I believe is there name. I suspect most the tuners get access to this ECU/TCU cracks all around the same times. I'm hoping they can increase shift speeds some...specifically down-shifts. I really miss the crisp down-shifts my DCT would do in my E92 M3, it was almost violent in comparison.

Thanks, I'll check them out.

I would do a transmission reflash if it had some safe parameters.

So what do you think about MP Stage 2 in the (M40i) compared to your M3 in the way they each shift? How much difference does a trans flash make?

[r33_RGSport]

Looking good.

[j1980mac]

I talked to ER about the DP fitment, and it may not have been installed properly.

I'll be going back to the same shop tomorrow to have them re-attempt installation.

It's leaking out the slits on the midpipe side top and bottom because the DP is not flush center.

--EDITED--

I went back to the exhaust shop and they reattempted installation to no avail. Still have a tiny leak. It's definitely a fitment issue. The DP may be about an inch too short. It's so close, but it's just not correct. I'll be sending in my factory DP to ER (shipping on them) and they are going to replicate fitment for it.

Here's my CSV log of the posted dyno pull. Not sure how to make sense of it.

Some quick figures -

Max Boost ~ 21.3 PSI
Max RPM ~ 7069
AFR Ave ~ 14.6 (kinda high?)

I don't have a flash tune yet (still on a Dinan Piggyback which is okay)...I've been waiting for others to give more feedback

Short comparison - the 7sp DCT in my e92 M3 shifted MUCH better. Obviously being a DCT that's expected as it also had a GTS flash on it. I think the 8AT is great around town (not as clunky) and it up shifts pretty quick. What bothers me at least is the lack to want to downshift multiple gears manually and the lack of crisp immediate shifts...there is a definite delay from when you hit the paddle to manually shift. For an Automatic it's really good, I would say it's probably 8/10th's of what a DCT is. If they could flash it to increase shift speeds a bit and be able to skip gears when manually shifting (ie: hit the paddle twice and it skips 6th -> 4th) I would be a happy camper.

I see the AFR is calculated, were they using a wideband in the tailpipe at all? If so they generally read lean since it's after the HFC. Also, your timing looks pretty low to me, there is also a dip between 5-6k that could indicate timing pull and/or knock.

I've personally never dyno'd on a mustang before but looking a bit closer at the graph it seems a bit strange you lose power pretty fairly rapidly past 5k. Almost every B58 dyno I have seen pull strong all the way to 7k. I might check with MP just to verify that is either by design (I suspect not) or the logs look okay. I'm obviously no tuner but generally seeing timing fluctuating and/or correction past peak torque might be something just to double check. For reference some of the other logs show tuned B58's running 10-12* of timing advance at redline, you are only seeing 3-4* which seems low to me.

Thanks for your insights.

I do believe that the timing reduction between 5200-6800 is due to the failsafe "torque reduction" (because of overboost).

Since this dyno run, MP has reduced boost between this rev range and increased timing.

Not sure if I explained that technically enough, but that's how I understand it.

Interesting, I suspect that is because when the vehicle shifts you land right in the "meat" of the powerband thus getting close the factory 8AT torque threshold. This will be nice when they have access to modify this and allow the full beans so to speak.

Makes sense the way they are doing it though. Did MP mention anything that once they have access to the 8AT logic they might be able to up to ante a bit since they aren't limited to having the transmission intervene?

Yes, right in the "meat" is right. Good descriptor.

MP did say that they have plans to up the limits on the 8hp50.

When I talked to Alex he did mention he is working on a trans. tune... interested to see how it works with the tune as I think I was overpowering the car last night after I shifted into 3rd doing a 0-60 run.

I think there's a good reason why ZF rates them at 500Nm. I'm not so sure I'm brave enough to manipulate the limiter.

I just put my stock intake box back in after reading all the stories. It is raining so much I am afraid I am going to get water in my engine. We are at 10" this week and still raining.

I pulled a 0-60 in the rain, spun so bad it shut it down and still hit 4.33. It may be better with stock box.

Wow, yeah, I think it pulls harder off the line with the stock box, although I can't prove it.

Interesting comment from ER, curious to see if they find the M40i is slightly different than others. Seems most B58 DP's cross reference 3, 5, and would appear X series (singe they have the same PN) so wonder if this isn't true.
