Mike,
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?

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.

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

did you doit or did you have it done . or is there a way someone could tell me how to do it and who to send the prom to. thanx for any help.

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!!!
