Anyone heard anything about this fueling solution? Looks like 2 x 2200cc injections in a small adapter fitted to the throttle-body. Wondering if this is another viable option aside from upgraded DI parts or full port injection.
I saw that and was thinking about it as well. My tuner said they are going to try one out on a ZL1 and let me know how it goes.
Well, if they give you feedback, please be sure to post it! There’s almost no info out about this. It looks like a simple install and less money than the other options; just not sure how power it will support. They claim over 850 rwhp.

I am not sure how much it will add to a stock fueling setup. I already have a Katech Goliath HPFP and XDI +30% injectors with meth. I am on the edge of being out of fuel again on C85. My tuner thinks I will be able to eliminate the meth and run E90 to make up for the cooling plus have a little room. I will post whatever I find out.

I appreciate it sir. I’m just starting out, and haven’t done any fuel mods yet. I have a DSX low side aux pump but haven’t installed. Was considering going full port but atlas is $$$. It’s that or hope to find used DI +30 injectors and hpfp. Either way big $$$.

All depends on how much power you really want to make

Like many, I hope to stay within the capabilities of the stock clutch to avoid changing it soon. 😆
I have a Kong x-ported factory blower with 2.3 upper, rotofab big gulp, and planning on long tubes. So mid 700’s rwhp I think is doable with that gear?

kits runs approximately 1800$. recently saw a full new in box motive ecu for the c7 with both harnesses for sale 900$ typically port injection plates cost about 700$ with injectors used no worries about will it work its proven for yrs. no need for an atlas unless you simply want the newest stuff out there or plan on making huge hp . im at 957 whp and the motive works just fine on full e85 with just 925cc injectors
im not a fan of sending liquid of any kind be it fuel meth or water down the throat of the blower. its designed for air and air alone. port injection not only ads fuel it also helps clean the valves and stems . buy once cry once
I’ve been waited on this product ever since it was teased in December 2025. My kit arrived 2 weeks ago and I immediately installed it. Super simple and straight forward.
Current mods:
Kong X ported factory blower
NX blower lid with meth injection into lid
Running 100% meth, not 50/50 boost juice
2.3 upper
9.2 lower
dsx flex on e50 blend
dsx aux low side 320lph pump
tsp blower cam with 32% fuel lobe
Rotofab CAI
103 NW throttle body
headers, catless X pipe, Borla Atak catback
FI interchiller
I might be forgetting something but you get the idea.
After installing Caleb Wisher’s kit, I ditched my entire meth setup and uninstalled the Dsx flex sensor. I opted to use the sensor Caleb’s kit had.
Tuning was also straight forward. My tuner, Derek Dunbar, had me dialed in within 3 revisions. No brainer to install. Just pinning 2 wires to the ECU. 1 of them was replacing my current ethanol sensor wire. You just have to install a custom OS via HP Tuner’s that Caleb emails over.
I’m now running on full E85 (it’s actually testing at 87% at the good gas station nearby).
I’m open for any questions. Ask away!

How are your MAT temps after a hard pull compared to the meth? I know you have an interchiller but did you notice any difference? I am spinning my blower a lot harder than you and my MAT temps with a chiller go up 30-50 degrees on a 1/4 mile pull even with meth.

Dang man, how much harder are you spinning than me?! Lol. I’m touching about 19lbs through my pulls.
I did just look back at some of my meth pull logs vs these E logs and it does rise a little more now. However, that interchiller does keep it in check. The recovery with the chiller is nice. One of my logs had 3 pulls on them separated by a half mile in between each. Just that little break got MATs close the my original pull.
I am only at 16psi making 925rwhp but I have a really efficient combo. I am running a 2.25” upper and a 9.45” lower. Mine recovers quickly but creates a lot of heat. I am looking at getting a Harrop 2650 to make more power and a lot less heat.
Hey everyone, It's Caleb Wisher from Wisher Performance. If anyone has any questions they need answered, feel free to ask away and I will do my best to answer.
I have had the AuxJection installed on my 2016 Z06..so far it has been a perfect mod. I had already done a BTR stage 2 SC cam, supporting mods, ATI lower, MPI sc lid, Halltech intake, MM catch can, x pipe with AWE touring exhaust, DOD delete, etc…car made right at 650 whp before. After AuxJection and a DSX low side fuel system, and and revised tune for the system and full E85 she make 750 or so whp. This is without headers and with stock cats! I wanted a road beast but don’t track it do any racing..this was the perfect mod to be able to run full E85, engine runs cooler, and runs much better!! Love this Wisher Performance and AuxJection!! I highly recommend it and the guy behind it!! Check out their web-sight and social media for all the testing that was done!! Fuel lines leading to AuxJection AuxJection spacer at throttle body

I sent an email last week and have been waiting for a response, can the kitbe purchased without the fuel lines? I eliminated the HPFP feed tube and have -6an lines routed under the supercharger. I can make my own lines to work.
