LPE 475: Should I Eliminate Secondary Stuff If Changing Injectors????? - ZR-1 Net Registry Forums

Hi, I have a 90 LPE 475 Package ZR-1 I bought in January 2010. I was using it for a Daily Driver in 2010 & 2011. It started developing what feels like a miss when the secondaries kicked in. If I would turn the Valet switch off, the noise would go away. I scoured this board & pretty much decided to change both sets of injectors, as I think they are still original. Now, a couple of Questions:

1) What are the "best" injectors to use? I don't care about a couple of hundred $$$ difference.

2) Would I be wise to delete all the secondary stuff since I'll be in there?

3) Anything else I should be doing while I'm there?

This is a really cool car. It was John Benders car when he did "One Lap of America" (Came In 5th). When I bought it, the seller really did not know a lot about it. It had all "Bottom of the Page" stuff from Doug Rippie in it. This is a car I will imagine I'll keep forever & I don't have to comply to Emissions Testing. Thanks in advance.
