To those who are doing Vortech how do these A/F readings look. I just wanted to get a second opinion.

Everything looks pretty good.....but a little lean from 2500-4000 rpm's....right where the torque curve is higher in the VQ engine. Maybe a little R4 software custom tuning in that area is needed for a little more safety.

Sorry,......I just noticed you're throttle position is not wide open at those rpm's so you should be O.K. .......as long as it does not happen under full load in that first gear when the TP is closer to 82. Maybe try to get the AF readings for those rpm's under the full 82 TP to tell for sure.
