So I have a tune from Chris and it is just a base tune and it idles were it should be but when I take it out and either when im cruising or trying to go wot my afr is bouncing back and forth and not reading right. Any ideas why it's doing this while driving? Chris said look somewhere else for the problem just not sure where? Any help

What kind of air/fuel gauge are you using? Narrowband or wideband? More info!

Did you try Resetting the ECU, driving with the stock tune (watching the wideband) and if everything is normal there try Re-loading the SCT tune? Any Exhaust leaks?

I have only 1 tune from Chris, I can redownload it. And I haven't checked for exhaust leaks.

Could you be a little more specific? Stock motor? Cam?
