FAST30859-8 Precision-Flow 87.8 lb/hr 960.8cc/min High-Impedance Fuel Injector for LS2, (Set of 8)

I ran out of injector @430 whp… stabbed these in my all motor LS6, then got a fresh tune, cured the sissy lean condition. Now more bald eagles fly from my pipes helping me lay down 80’ freedom stripes at every green light.

Can't verify the performance but they fit better that the previous aftermarket injectors I had in

Buy a better brand that actually gives data on thier injectors. These will either leak or not fire at all. I bought these in 2019 and just got my build done, so too late to get a refund. I was dumber in 2019 when it came to buying stuff. After Taking to my car tuner realized couldn't find any data or spreadsheet on these injectors, not even on fast website. And to beat it all, 1 injectors wasn't firing at all and 1 injector is leaking. Fast only makes good intakes. Stay away from thier injectors. I ended up buying some ac delco lsa 56lb injectors

Injectors work perfect right out of the box. Afr is stable and consistent on both banks based on narrow bands and wideband. Duty cycle is half that of factory injectors. Tuned with hp tuners on a Twin turbo corvette

Took an extra day to get delivered but was the right product .

Exactly as described

Perfect

Does not come with any data logs and they don’t have any so makes it a pain to tune your car

Top quality replacement part for a C6 Corvette at a fraction of the price of an original set.Easy to replace, it should not take more than about an hour to do the job with a good mechanic.
