Avtandil did get back to me and mention that it does look like I may still have a boost leak somewhere, so I'm working on assembling a boost leak tester that will produce a similar enough manifold pressure to really identify where the issue lies.

*ninja edit - I also had a CEL pop up twice during start-up (cleared and popped again): "104301 absolute pressure sensor, intake manifold, plausibility" which again leads me to think that there may be a leak that popped up during the logging run as it's the first time since I've had it back from the mechanic that it's seen full boost.
No need to apologize, it was just an off the cuff remark and was never intended to ridicule you for posting logs of a base tune. We apologize if it came off that way as well. Sometimes posts/texts can come off in a different tone than what's actually intended. Our intention was to simply point out that sometimes it's best to have the tuner review the logs based on his maps to find if there is in fact a mechanical issue or boost leak which it seems there is based on his overview.

Let us know if there is anything we can do to help diagnose the issue if needed. We're always here to help!

Getting ready to get on the dyno with my PS2+/Dorch/EU5 setup and was told the following by my tuner:

"You can run E85 but power is going to be limited due to stock LPFP and the EU5 injectors, which can only flow about 20% or so more than stock injectors.

If you want max power E50, if you want convenience, E85."

Any advice/feedback?
Thanks!

I'd go for pump E85 convenience and also spend time learning more advanced log reading. This way you can bring up points and push your tuner for the best job. If your goal is maximum HP or fastest times then go the E50 route.

I was told much the same in regards to the LPFP, so I opted to install a Precision Raceworks Stage 3 for piece of mind. From what I've seen this may vary by tuner as Halim himself noted that you could run straight E85 without the addition of upgraded HPFP's, but as Kratos mentioned in a different thread you run the risk of higher fuel pressure targets potentially locking up the injectors.

I'd imagine that the stock LPFP could be adequate depending on the ultimate power goal, but even PI requires the addition of an upgraded LPFP in order to flow well enough for high level E85 tunes.

Just watch logs for LPFP struggling and cap it a little short of that.

Welp I just wanted to quickly share my dyno tune sesh with the maestro Paul Johnson! 🙌

This was the last run after ~ 10 or so pulls as we worked on the 93 map prior in pretty hot/muggy 90+ VA weather😅

DCT F82
PJT E85 tune
PS2+ (redesigned 2020 version)
Dorch HPFP kit
F10 M5/EU5 injectors
NGK 97506 at .019"
VRSF DP's
AA single midpipe
AA 3can muffler
Stock cooling and stock intake with drop-ins 👀

That's essentially all power upgrades wise.
Less is more 💪

NO PI OR METH! - I was not interested in any potential risks and complications associated with supplemental fueling or secondary controllers. These results were made at "only" 27/28 psi with no issues with fueling limitations.

Stay tuned my friends 🤙

Have to look it up but pretty consistent 600/630ish

Where abouts in VA are you located man? I'm down here in the Hampton Roads/Virginia Beach area, and apparently the 93 octane fuel out this way is shit.

The boost leaks were identified and taken care of, but the timing is still breaking up in the high rpm band. Both Cary and now ABP have mentioned fuel quality seeming to be the main culprit on the 93 tune, so I'm trying to supplement with 3-4 gallons of 100 octane in order to boost it. I'm shooting in the dark though as the tuner crowd around here have stated the 93 in the area is some kind of reformulated crap that might be closer to 91, but there's no way to be certain just how off it is.

Even after adding 3gallons of 100octane to a tank of "93", the conservative 22.5psi tune he sent me still breaks up, albeit not as bad as before. This shit is maddening 🤬

Buddy, I'm the mad scientist of fuels.

Your mix is too thin for the bump up you want. Let's say your 93o is really 91… Mixing 3gal of 100o(0%E) with 11gal of 91o(10%E) yields 14gal of 93o(8%E). Use 2gal 100 with 5gal 91 and you get 93.5o… using 2.5gal of 100 makes 94o.

I'm your case I would use the 5+2.5 mix for 94 octane. Alternatively just go to Insinger Fuels and buy a pail of Stinger MC3X (100o pure gas), or Sunoco 260GT (100o 10%E), or VP C20 (97o all gas) or C10 (100o all gas). C20 is probably more economical. With all-pail you will KNOW that fuel quality is there, and let your tuner know so they can see if timing improves. Having too much octane can't hurt unless they juice up the timing above what 93o can handle.

If things stay crappy with all pail fuel then see if plug gaps got funky… I've seen gaps shrink after being freshly hand gapped by me, installed, run, and re pulled. Some of my .21s shrunk to .19s.

I appreciate the feedback brother; I actually downloaded the spreadsheet that you posted in a different thread too, and have been running through my calculations on it. The Sunoco out here that I used has 100octane (with 10%E), and after running the numbers you're likely right that it's still too thin. That and I'm only able to speculate on the actual octane, so it's a bit trial and error.

I did install NGK SILZKBR8F8S's gapped at .020 a couple of months prior, but I may take your advice and recheck the gap this weekend just in case.

Awesome results on this! Any thoughts on this M2 Comp with Nostrum HPFP kits and the Stage 1 injectors they offer? Debating which HPFP to run while also upgrading injectors. Trying to avoid going PI and would really like to utilize Flex Fuel.

I heard that the Stage 1 injectors only flow slightly more than an OEM EU6, but not as much as the EU5. Their unreleased Stage 2 and Stage 3 injectors exceed EU5 (M5). Gotta wait for Stg2 or 3 for big turbos. Stg1 only helps stock turbos on E85 a little.

Just to share some happy with you. I was at the engine lab today and we're getting closer!

New KRAS55EVOs came in, head is all cleaned up, Dorch kit is ready, and EU5s are cleaned/tested and back from RC Fuel Injection. Hopefully I can break it in next month. 👍👍👍

Is it good practice to clean/ test brand new injectors?

That will probably be my next upgrade.
