Because larger injectors can't be fine tuned as well as smaller ones. I went through this with my CTS-V. Everybody was saying to get ID1000's, but when it came time to tune them, they couldn't be tuned right and I had to get smaller injectors. Just like a carburetor or exhaust, bigger isn't necessarily better. The minimum that meets the engines needs is best.

The only thing that could screw up a ID1000 tune is a bad MAF.
Next size down, I think either 750 or 800 tuned perfectly fine. The 1000s were just not happy in there. We even tried generic knockoffs.

I appreciate you taking the time to explain this to me. I've been out of the scene for years so I guess I have quite a few questions about this stuff. Nice to know this forum isn't completely dead.
