5.1 motor break in

hi I have a new set of 5.1 I got from tim at TRE and was woundering if there to big for a new motor break in ,or should I send my old ones in and get them fixed up with smaller tips. why I'm asking is I just had my old ones tested and there no good and I was planing on useing them for break in, but now I don't know what to do, one injecter needs to be replaced not sure what was wrong with the rest but they didn't flow the same. please let me know what the best way to go is thanks

It is no problem to break in an engine with the 5.1's. Nothing really changes in terms of fuel delivery at low speeds and especially idle.

Go right ahead and use them.

that good to hear thanks alot shane
