I would love to run straight e85 and get more performance then having to mix for my e30 tune from torrie

Well... I'm stuck. My indecisiveness is debilitating.
Either way I have to dump more cash... Just how much $$$ vs gains ratio is where I'm at. I don't mind paying if the the requirement (hpfp) is real and the benefits (gains) are tangable.
My best 1/4 time 12.8. Best trap is 109mph. (On LMS Meth tune)
Maybe I'm just being unrealistic/unreasonable in my expectations. But basically whatever (if anything) I'd be able to do to improve on that by at LEAST 5 tenths is what I'm looking for.
Here is what I find odd... My car runs great on this Meth tune. It has been the least problematic tune for me even if NOT running meth (which I am not recommending or condoning). But V11 and V11 HPFP adjusted still sputter out on the top end. I don't understand why if the meth tune is supposed to be more agressive (which the seat dyno would say it is).... We'll IDK. That's where I guess my skepticism lies when it comes to that 1.6k $ hpfp... Plus they still want meth for running e85.

What are your goals? See my signature and that is what I have done with Brad's E30 tune. So those numbers were also with a popped off boost reference hose (should go even faster)....and I am plugs, K&N drop in, and TUNE only.

What was the DA on that run?
I ran a 12.799 on their V11 93 octane tune with the HPFP, CAI, 160tstat, and 3BAR.. the car was also heat soaked and my launch was not the best with a mid 1.85 60ft.
With meth you should be mid 12’s unless your elevation is killing you...
My meth injected 2010 ran 12.4’s on the LMS meth tune...
And you shouldn’t be sputtering on the top end with the LMS meth tune? Unless you are injecting way too much meth as the system is a progressive system.
With the updated E30 tune from LMS I suspect I will back into the 12.4’s easily with my 2016.

They want methanol for supplementary fueling due to the e85 causing it to lean out.

Jordan is correct. The fuel system can’t support full E85 with an aggressive tune. Spraying meth will take the load off the injectors and fuel pumps...
Are you running their DPM setup? Or a single nozzle?
Before making a purchase on the HPFP to support full E85 I would make damn sure they are willing to tune for it without the DPM setup... they may not as they are phasing out support for their single nozzle setups.

Faster than stock. As long as the FP holds out right?
I aint dragging the car on E85 thats for sure.
Maybe we can coin the phrase like "Save the Whales" Except with a low boost E85 tune its "Save the Snails".
She starts good. Runs good. Cant wait to load the next Rev.

LMS runs way too rich to support E85 on the stock system... lean it out a bit and adjust for ethanol stoich would free up some...
But I would say demanding 15psi (and holding it to shift) with 23 degrees of spark is a fairly aggressive. LMS can barely do that on the stock fuel system with how rich they run.
Edit: they demand 13.7ish psi on their base V11 tune and people have hesistation issues due to fuel pressure dropping. Their tunes run at .74 lambda under wot...maybe a hair richer.
It’s enough to turn the tail pipes black after a few runs lol.

My goal has always been to run low to mid 12s... I am consistent 12.9. 12.8 is best 13 flat is lowest. Idk DA was high I posted it here somewhere. Ill check in a bit and edit.
To be clear the meth tune is the best tune I run I have very minimal to no sputtering even with NO meth actually being injected...(they do however scaleback the shift point on I believe the 2nd to 3rd shift several hundred rpms) I do have and have always had sputtering on the top end with the V11 and V11 HPFP adjusted tune tho that was covered in earlier threads.
Having said that I recently tried running E30 in my tank with the normally problem free Meth tune and low and behold the return of the top end sputter. Which in turn brought me to this point.

Yea... That's where I'm at... I'm considering AJP for E30 tune. But concerned that if I am indeed having hpfp fueling issue that it may be all for not... Then as some have stated I'm not sure whether the sputtering issue is a "tuning style issue" or a true hpfp fueling issue. I have no data logging equipment tho because of the tuner I chose so here I am. It's seems as myself and SBS have had a similar path. He does have much more first hand experience with different tuners however.... Here I am trying to cheat and lets say not have to go through all that and achieve optimum results with minimal expense...
