Bosch "Lightning" 42.5 or Lucas 42.5?

I was wondering which injectors are the better of the two. I found a really good set of the Bosch injectors and almost bought them. I am using them for my turbo build and this is the last piece I need besides my pump. So what do you guys thinks? I can get a Flow matched set of the Bosch's for $170 or Lucas 42.5 for $250. So people that are boosted please chime in. Also which ones will be easier to tune?

Here is a pic of the Bosch one's I am talking about.

I'd take either, just make sure they are flow matched and ask for paperwork with them. People will say anything to sell, that is one you want to call them out on man to make sure you are getting what you paid for!

It's always a tough call on choosing injectors. Here I believe I would try the Bosch, if they are flow matched, especially.

iirc, those are the same length as the Trail Blazer 28 lb injectors, meaning the tip of the injector protrudes into the LIM a bit further than the Lucas 42s did, which seemed to help at idle, and the spray pattern is probably better.

Also, I did have one bad experience with the Lucas 42s purchased from ZZP, but they were not new or flow matched.

Well I ended up getting a hold of a friend in Cali and he sold me 8 - 42lb Lucas injectors with o-ring spacers for $175 shipped. They are all "Brand New" and never installed on anything. I have heard the Bosch injectors do have a better spray pattern but I searched forever today and could not find anything that would let me swing one way or another.

I would just get Siemens 60's instead if it were me.
