I have a mail order tune in my 2012 Colorado for now. Midmount 70mm with meth. Having issues with timing mostly. You'll see in the scan that timing spikes down to zero during boost. Anyone know why?

Here is a short pull I just made in 1st-2nd gear. I changed my meth nozzle from 3gph to 7gph before the run. Seemed to help, but as The Sultan has pointed out, I am still misfiring on bank 1. Plugs looked clean on one side, sooty on the other. They're Bosch platinum 6 heat range, gapped .035. Gonna log MAf Hz next. I'll be back

This is latest scan with MAF Hz 9.00 and above multiplied by .95. Wideband AFR gauge shows richer (9.5 AFR) during boost with this change. Don't understand why...
