Well I finally got the wideband installed in the truck. Looks like my tune is on the rich side. What a/f ratio are you guys with maggi's running at wide open throttle?

 

Mine seems to like 11.5 in its peak torque range and feathered to 11.8 up to the shift point. Hard to do with methanol spraying. If I can keep it below 11.8 and above 11.0 I'm happy

 

I was told that generally your looking for around 12.5 but after reading the tuning manual i was wondering if it needed to be slightly lower with the magnacharger making so much heat. Should have more power available in the tune from what i can tell though. In the video I spun at first and let off and rolled into it.

 

12.5-12.9 in a N/A setup. 11.5-11.8 for any FI setup. GENERALLY.

 

Dang man, that's a fast Z71. What all you have done to that thing? I'm hoping to get into that range with mine. Your using meth, any nitrous?

 

Nevermind i found your link. Nice truck!
