I need help on finding new injectors. I don't know the good from the bad...I'm running a tsp 233/239 cam and I'm at like 96% duty cycle now....I'm going to be running a dry kit so I need to upgrade injectors. Brand, size, cost, and where to buy would be great thanks guys.

FIC 37# injectors or 42# and a racetronix 255 kit w/harness and you will be set

that being known 42# injectors would be the best match, as a 255 pump maxes out at 8 x 51# injectors. Most injectors are rated 43.5psi and our rail pressure is 58psi... so a 42# injectors becomes a 48# injector.

having included that in your original post, I wouldn't have mentioned the pump...details, this time it didn't matter
