26psi is not "conservative".
I'm very confused why the spool up is so delayed as well - what elevation are you at?
I don't see an O2/DP in your mod list, are you running stock? If so, change that immediately lol.
You have a built bottom end, why are you so worried about being conservative? Stock these things will run 375-400tq all day for years to come.
I'm on 91oct and Cobb Tuning got 414/350 out my my MHI on their Mustang Dyno. Not every dyno yields the same numbers regardless of "brand" but your graph concerns me and makes me feel bad for you with all the $ you've put into your baby.
EDIT: Honestly, not hitting peak tq until almost 4300rpm on this turbo is just wrong.....seriously, massively wrong.

Why are these massively wrong? Where are you peaking? If I could get sub 4k I'd like to know! Thanks.

No, that's the dynograph I was referring to. His baselines were much higher hence the "higher" numbers at the end, however, the net change from baseline to MHI is actually quite similar
I haven't seen any dynos with the MHI hitting peak tq until after 4000 rpms. Most of the dynos in the below MHI dyno collection thread are around 4300.

Me too...Dropping the X off at Boostin tomorrow for the E85 tune. Dyno will be posted next week
Should be interesting...although it sucks that the "E85" that the Chicago stations are selling is really E70. I know that Boostin can blend it with the E98 that they have in store so we'll see
you cant compare numbers from two different mustang dynos. it would need to be on same dyno. there where local mustang dynos here in tampa that read higher than the local dynojets. mustang dynoes are pretty much useless for comparing numbers from dyno to dyno. dynojets are best for this.

Just saying, I get what you mean but that is a staggering drop in final numbers based on the PSI and plenty of other supporting information to suggest higher expectations.

And for reference, my car was dyno'ed on the same dyno and made ~30whp more on the same fuel at the same psi with the same mods. That said there are many other variables - weather, settings, owner preference on how conservative, etc. - that factor in.
At the end of the day, if the owner is happy that is all that matters! There is a tendancy to try and pick apart any dyno that is posted - too little hp, too laggy, drops off too fast, too little area under the curve, my friend's did better, etc. If the owner is happy with the $ they spent, that's all that matters!
More importantly - E85 results!!!!!!!

And question on your E85 vial pic. I assume there is some settling at the pump - i.e. a gallon or so in the plumbing as well as the underground tank. Given E85 doesn't have a huge demand, a tank could sit for weeks or months. Do they have a way to agitate it to keep it blended?
That's good question. I tested the E85 once I was done filling up the 10 gallon jugs so I don't think there was an issue with residual/unmixed gas from the lines. In any case, I've always tested the E content when I fill up since it's pretty easy and quick. In the past, I had multiple tunes on my STi for E70, E85, and E95 since that was the variability that I experienced here in Chicago in the past. I'll have to speak to Devin and find out how he tuned it and what tolerances the tune can compensate for.

lol...The car should be ready for pick-up on Friday so I will post ASAP. I'm super excited, especially since I just told them to go ahead with the Comp clutch. I figured after putting all the $ and effort, why be help back by something silly like a slipping clutch.
