bigger injectors=afpr

[missouri_dsm]

I was planning on getting bigger injectors(550's) and heard on a 1g you have to get an afpr. I dont have the money for the afpr right now so should i wait and get both or can i put the 550's on without it for now?

you will need the afpr if you get a walborogh 255.

The larger injecters will at best cause more pulsation in your fuel. They will not cause more return flow.

That said larger injectors without an upgraded pump might not go so well.

stock fpr will work with a 190 in most cases.
