Default Which injectors are these?

I bought the car with these injectors so I dont know for sure what they are. I thought he said they were 19's, but after installing my wideband, well I'm running in the 10's at wot with gt40p heads and a mild cam.


Is this a stock MAF?


I've noticed the idle is not steady and it stalled out once. The afr bounces from 13-18 at idle. Should I get a larger diameter MAF calibrated for whatever size injector these are or recalibrate the stocker?

The Tech article about injector color/size needs to be update.

Thats what I'm guessing, but I've seen 24s for sale that were grey. Is it true that the water temp sensor can make you run rich? Cause I cracked mine and jb welded it back together.

yes the coolant temp sensor can make the engine run rich. If it thinks the engine is colder than its it will give it more fuel. I have heard that the blues injectors are 24's but I don't know if it is true.

I have a 5.9 out of a dodge truck sitting in the garage. It has gray injectors. I hope they are 24's. They plug up like a ford.
