Trying to narrow down what is going on with the LT and ST numbers. Both go way into the negative at times and B2 is normally more drastic. Tune and logs attached. Where do I start??
Thanks

Tune your fuel trims, nothing wrong here. You've changed the VE of your engine, need to adjust to get it back to specs.

I was afraid that may be the case...I dont have wideband O2's so what would be your suggestion as a starting point in adjusting the fuel trims? As in values/tables? Thanks in advance!
