Wisher Performance Auxjection
I stumbled across this over the weekend:
https://www.wisherperformance.com/products/auxjection?variant=46211491430558
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.

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.

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?

That will work fine at that power level.

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 brain 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!
