AuxJection | LT4 Stock Supercharger

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.

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!
