Just wanted to have everything looked over to make sure I have the correct data for the injectors, map sensor, etc. Any additional help would be greatly appreciated.

Here is a short log at idle, I can't seem to rev the car over 2k rams its almost like a light two step

Looks like you cut the IFR in half then only added 50% to the flow rate multipler x volts table..Quote:

Enable fuel trims. They can at least do some adjusting for you.
Why is the wideband showing an absolutely flat 12.92? There's no way it's that stable
It wasn't connected at the time. I saw that yesterday when I was looking at the map, the injector data was done by the previous tuner, not sure how it ran so well when it was na now haha thanks for the response!Quote:

Yeah that's probably easierQuote:

Did you go SD or still using a maf?Quote:

I added a honeycomb to help straighten out the air and that helped but it still bounces around a lot and the AFR's jump around with itQuote:
