Default Fuel injectors

Did a bunch of reading today about fuel injectors. Visited FIC for additional data, but still some questions.

I have a stock 1994 6 speed.
do I replace with the 24lbs injectors.
Can you use 30 or 32, or is that a bad idea.

Do you have to go into the computer and changes some data fields with the 30/32 injectors.

Saw a wide range of prices. Based on better injectors??
24 were $389. 32 were $440. 30 were $189

Any help would be good. Also do we use LT1 edit to change the values?

Absolutely!

You will gain absolutely nothing by going to higher flow injectors.....even with a tune.

No power or drivability gains to be had at all!

If your current injectors are flowing OK, then leave them alone.

Use the OEM #24 injectors.

Larger fuel injectors are for modified engines that require more fuel. Using larger injectors on a stock engine will result in, loss of performance, loss of fuel economy and poor emissions.

I have a set of Bosh stainless body injectors, I took out of my 90 looking for idling problems, they were just put in before I got my car.

I will sell the set for a 100 shipped.

I would not run a stock Rochester Multec Injector. These will work just fine, and be quite an improvement.

Seems weird that these are not listed on the LT1 page, but are in fact for LT1.

They are Delphi http://fuelinjectorconnection.com/sh...p?productid=45

Above is from the papers I received with my car, these are what he bought, whoever installed them used the wrong donuts and they were sucking air.

You would need new donuts to install them, the rail clips are on these injectors, I installed were a different type,I didn't need the clips.

the first person in line, and it always has been here at the forum, was whomever PMed me first, and someone did.

If he drops out the next one gets them..... again I'm sorry for the confusion. B Guzz
