How did it run after they were removed? Did you notice a sizeable increase in power? Is ther vehicle smog issues in texas that could be a concerne here?

Thanks!!!

The car runs great. Although I had the secondaries removed when Mike did my 402 build so I don't have any information on before and after that would be useful regarding a stock displacement engine. The 402 barely failed the Texas emission test so I had Mike burn an extra chip leaning out the tune so the car would pass the emission test.

I just replaced all 16 injectors. 6 of my 8 primaries were shot and 2 of the 8 secondaries were shot. The motor was running so sick I was afraid I had other problems. With the new injectors I have noticed the following:
Motor fires immediately sometimes (but still may take 2-3 cranks other times) which it never did in the 7 years I have owned it. Power is there again which may be slightly more but not a major improvement from when the motor was well. I purchased my injectors direct from R/C in Ca and got then for $68 each which was a slight savings over a seller.
Kurt White states that R/C injectors are simply the best >

I've heard that running w/o the secondaries might cost you a little low end grunt....even if it does, at least you no longer have to deal with that crazy secondary vacuum system and the issues that go along with it.:???:

it's not worth much at all in terms of power, but the car can easily be reprogrammed to run without them

on a stock displacement engine you lose some low end but on the LSV 390 low end torq isn't much of an issue

I love running without them car developed a bit more mid range torq

I am also considering this as I need to replace injectors so a good time to try. My thoughts were to get an extra set of injector hsgs. to experiment with and save stock setup. Also clean up and p&p top end for complete pkg. I heard newer versions take the same injectors (all 16 the same) if so that would simplify things. Any expert opinions are much appreciated!!!
