Wisher Performance

The whole kit and install is flawless especially with the right fueling system and supporting mods makes your car an absolute rocket!

Product fits great, good quality and comfortable. Highly recommended!

Total Game changer! Very clean and easy install. I Have installed multiple kits and every one of them gains over 100Whp/100Wtq utilizing AUXJECTION.

The products from Wisher performance are top notch. I would highly recommend WP for all GM performance tuning and fuel systems.He does all the tuning for the vehicles that I build for my customers.

Worked as advertised. 49 rwhp gain just by swapping to flex fuel.

I just received my first few kits and was pleasantly surprised! The auxjection plate is O-ring sealed on both sides and mates up to my Jokerz ported snout very nice. No more making a gasket or using RTV to seal the the 103 throttle body to the snout with the oem gasket groove ported away. The wiring harness is oem quality nice, the fuel lines are cleanly put together. I have not installed the kit yet but first impression upon unboxing is impressive and flawless!

So far so good! The shop owner/car builder was very impressed with the unit. It was his first time installing and tuning an Auxjection unit. The added fuel and the ability to run full E85, the car made about 100hp more with AuxJection over pump 93.

Wisher AUXjection works exactly as advertised. I recently used it on a 900 WHP 6th gen Camaro build, and it performed flawlessly. From a tuning standpoint, the integration is seamless no workarounds, no gimmicks, and no headaches. It does exactly what it’s designed to do. Highly recommend it to anyone looking for a reliable auxiliary fueling solution that also cuts down manifold air temps!

Incredible system, works exactly as described

Great thanks

My boyfriend loves this shirt cause it’s so breathable and wisher performance was quick to message me back when I had an issue with logo but they made it right 100 he had me order him more

I own a 2018 Chevy Tahoe premiere. I had it supercharged (750+ at the rear wheel) lowered, and 24 inch wheels put on each corner of the vehicle. However, the original tune did not stick. It would fall in and out of tune- a major pain in my neck. However, a friend of mine told me to go see Caleb at Wisher Performance- the best thing that ever happened to my Tahoe! My Tahoe is running better than when it was brand new. If you have any performance work that needs to be done on your vehicle, take it to Wisher Performance.You won’t regret it!

Works fantastic! Easy to tune and the kit is top notch. I like this solution over meth and port injection due to cost factor and reliability. A+ product!

Everything was as described, included all needed tools and parts to complete. It is sleek and has an extremely clean look when installed. Wisher Performance is also incredibly easy to communicate with and always timely!
