What are the better injectors bd or ddp?

 

I have ddp,s in my truck now. stage 2 and out of the set i got 1 bad one and had to buy another as ddp made every excuse not to take care of it!! honestly not impressed with them as far as perf. goes. I am getting a injector knock again so i am going to shop around!! ddp,s have about 5000 miles on them and less than 9 months old!! btw i have nothing good to say about there customer service!!

 

BD is probably better quality but will be more expensive than ddp
