Nick,
I had the exact same problem and went through what it sounds like you are. I had to bring the fuel injector flow rate down (trick the compputer into thinking you have smaller injectors) and then decrease the VE numbers. I found the answer on some other board once and it saved me. Basically,, once the VE numbers cause calculated airflow to reach a certain value, the computer isn't able to process it, and throws the code. So by triccking the computer to think it has less airflow, but making up for that by also making the computer think there are smaller injectors. For me, I have 95# injectors, but have the numbers for ~65# injectors. I hope this helps. It is a tedious process as well, if you already had your VE numbers tuned in pretty well before as you then have to retune.

Anyone know what that "certain value" is?

For a while I was pondering how Nick could be flowing 4.10 gm/cyl as rough calculations told me that would be somewhere in the 2000 engine hp range.

again, why not just disable SES for 1514 code? Worst i can imagine is throttle getting stuck open.. then just shut down.

Disabling ses...so you have no light, but wouldn't it still go into reduced power mode???

Asking, cause I had to cure a 1514 related problem today on a car with a fair sized cam and maggie.....I didn't think that disabling the light would cure anything???

Are you sure you have the table set to 4.1?

NO, disabling SES would keep it from going to reduced power mode. Setting no MIL light would make it just not show a check engine light.

I know this for sure, from personal experience.

You need more experience. It will do NOTHING to stop the PCM from going into reduced engine power mode in this situation. All it will do it stop the reporting of the DTC but it will still shut down.
