I thought the O2 was already disabled, not able to check now but will later a report back.
Thanks for the help.

Well I jumped the gun, getting misfire with both tunes.
Seems to happen mostly at idle.
The SES light comes on, but shortly after driving light goes out only to come back once stopped again.

I have an issue with a 408ci I'm trying to dial in, if I switch over to MAF only the engine misfires.
If I tune only the VE I don't get any misfire?
I'm trying to get my lower rpm fine tuned with...
You will get more help if you post the current tune file with the log file.
And this post most likely should have started in the transmission section.
Thanks Ed, I'll give that a go
Do you have a idle log file you could share?
Got the wide band hooked up and made some adjustments.
The fueling is starting to come inline but still need some more work.
The in park and neutral seems pretty good but when I put it in drive and...

The throttle...
I have made the changes for the injectors based on 58psi fuel pressure and return style.

Yes I got the injector info right from DW.
But I'm just now finding out the fuel system has been converted to return style so I will need to adjust the flow rate right?
anything else that needs...
Yes I added to the VE didn't want it to be lean, thinking it would be safer that way. not having any experience with larger than stock size motor.
One thing I had read suggested lowering the VE in...

Badbowtie,
Do you have a pyrometer? if you want to bump power up you need to keep an eye on your egt's

Paul ,
Here is a tune my dad tried in his 02 he really liked it said it was "real snappy" down low.
We removed it because it limped his stock trans sometimes.

Thanks
