Thumbs up bootmod3 Stage 2 93 octane OTS map - dyno - 663whp / 666wtq

Thought we'd share a dyno from a recent tune on a customer car in Florida done through our dealer Miami Performance Inc.

Car: M6
Mods: Downpipes, bootmod3 OTS Stage 2 93 octane map
Octane: pump 93 octane (98RON)

Boost on this run hit 24psi down low in one spot but levelled off to 23psi by ~5800rpm, 21psi at 6600rpm and 19.5psi at redline.

One item to point out, at this power level blending in ethanol is not a good idea as you can see in the bm3 log posted below that the HPFP (high pressure fuel pump) is falling under target to 1600psi from the targeted 2900psi. If you've ever dealt with misfires on your S63tu when pushing power, and not using meth or secondary PI injection to supplement and help the fuel system, then we suggest dataloging and paying attention to your HPFP pressure. Midrange power/torque we feel is already maxed out due to where the HPFP is sitting unless we lean it out a bit to 5500rpm and to go higher in that area you'll need meth which is easiest to install or a PI kit that we don't think exists for the S63tu today yet.

This is the current state of our OTS Stage 2 93 octane map. We're looking to get a bit more dyno runs in as its very likely there's a few more reliable ponies in there at 6k rpm. Let us know if any questions at all.

So you are saying at those power levels the fuel pump is already maxed out? Lots of stage 2 flashes running around with more power than that.

No, think we have more power in it top end in the 6k range and up even on pump 93. Each pound of boost seems to be another 20whp on the S63TU. Another 2psi at say 6k rpm and it could see another 40whp at peak

Just shedding some light on numbers we got and sharing data with datalogs of the runs (you can click on the images and take a look at the run btw). The fuel system limitation in midrange (3-5k rpm range) in terms of the fuel system and the high pressure fuel pump is what it is.

Most if not all going past these power levels seem to be doing it with meth, either JB4 controlled or Aquamist or similar, which makes sense as it helps the HPFP from dropping out and you get the octane to push harder.

This is on stock turbos also, not upgraded Stage 2 turbos.

Thanks for sharing your data with us.

So what is the minimum safe fuel pressure at redline? I assume you're saying 1600psi is too low for your current power levels? And when do we need to look at replacing stock injectors; not sure what the stock flow rates are. I know you guys are still in beta testing and appreciate the info.

You're welcome.

No, didn't say 1600 specifically was too low but when pressure dropped to about 1100-1200 the motor would misfire so 1500-1600 might be considered a limit where you can run it at this power level without any hiccups. This Stage 2 93 octane map is running really well and strong as you can imagine compared to stock with just downpipes on the car.

With meth there's quite a bit more on the table as its used as a bandaid for this fueling limitation. You could also run a bit leaner AFR in that area which will help.

With direct injection injectors on this motor there aren't any injector upgrades available You're thinking port fuel injection motors Wish it were that easy as many would opt to do that and upgrade in tank pump/pumps and run full E85 with big power. Instead, people throw meth on or add secondary port fuel injection with conventional injectors to help the OEM fuel system cope with power demands.

Just sharing some in-depth data on the fuel system on the S63tu seeing it struggle to keep up at this power level in midrange even on pump gas. If you threw in ethanol on top you'd max the fueling out even sooner.

If you limit mid-range torque then you help preserve your clutches as well as not having this fuel pressure problem - seems like a good idea to me

Win win If you upgrade them though you're back to square one with the fueling No issues with slip here though. TCU is seeing true load and maxes clutch clamping pressure.

What is the reason behind it dropping down in the midrange then picking back up to the target again? Is there still plenty of room up at the high end of the range, i.e. With stage 2 Pure turbos

This is an M6 in Houston with downpipes only with DME tune. No stack, no meth, a is on pump gas.

I also know a few others on the same tune and mods pushing the same numbers.

EDIT*** ignore this post*** you said power band and not power. Misunderstood. Lol

HPFP is a limitation at this power for the target AFR. As you can see in the log we're targeting low 12:1 there. 12:1 requires more fuel under full load than 13:1.

Thank you.

If you look closer at the log 24psi is not sustained boost, holds it 4850-5160rpm Stock TMAP sensors on this car and no other modifications outside the ones listed. 24psi in the top end would pick up another 30-40whp if the HPFP doesn't nosedive and can keep up. With meth on the car, different ballgame

Thanks for sharing. Did you get a chance to get some logs of your runs and look at how your HPFP pressure is doing?

Glad you logged AFR on that dyno. I see your car is running 1-1.5 points leaner AFR through midrange than our runs in this thread. That's what we were hinting at earlier. Running 13-13.5:1 through midrange instead of 12.1-12.2:1 will most likely lift the HPFP higher and help on the torque. Then again as some mentioned, maybe clutches would start slipping as this is a DCT Is yours a 6MT or DCT?

On the Pure Stage 2 run I see your boost is tapered lower to higher as RPM goes up. No AFR trace unfortunately but that's another way to keep that HPFP from dropping out and take advantage of getting more power in the top end.

If you guys have any other runs with datalogs to share that are on pump gas specifically and stock turbos/downpipes that'd be great. Without datalogs its just another dyno pull and it won't bring much value to the discussion.

Its a ps1
I have manual



The pic above is not my car but my buddies car on stock turbo n clutch.

Yes idk if they have done logs (owners of cars)
But only data we do is race cars on event if that helps. Lol.

Wxactly.


Follow the instructions of your tooner and it wont blow up.
Logs n dynos are good table to see improvement and changes. But numbers dnt mean anything if it cnt perform on the street

Here are a couple of my graphs. I did not know to ask about the HPFP a few months ago; only log I see on the graphs are AFR. But I will try to ask my tuner Mission Performance about the fuel pump and what they logged. The dyno tune was for 91 pump though.

Stock turbos, stock downpipes, 3 gallons E85 + 91.
