Time to upgrade injectors when I do heads. My injectors are at 106% duty cycle now. I was told by my tunner to get 30#'s. I was thinking about getting flow matched, so I can put the ones that flow the most in the rear clyinders. I was told Ford or SVO injectors. Is there a difference? What other types are good and where is a good place to get them? I have checked the sponsors, just a lot to look through for who has the best price.

 

I went through Ebaymotors...did a search for Bosch 30lb injectors, and found a company by the name of Deatschwerks that flow matches sets of 8. They are used injectors, but work great for me. I put the highest flowing ones towards the back just like you said you would do.

The biggest problem with your duty cycle is most likely your fuel pressure though. Since I started monitoring mine, I can see a steady 6 psi drop at WOT (drops to 52 psi from 58). Lack of fuel pressure is gonna drive your duty cycle up since they have to stay open longer to get the fuel in.

I just need a good way to get a regulator at the rails instead of in the tank that doesn't cost a fortune or make me cut up my entire car/fuel tank to do it.
