A/F? About to go boom?! Safe or not?

I think...

When I did my last tune during the summer my A/F was in the 11.6 range. Now I haven't had a winter tune since then since I am about to head back to Texas in 2 months.

I noticed the past couple of nights that my A/F was in the 11.0-11.2 range at WOT in San Diegos 55* weather.

How bad is this? Is it bad to go to the 1/8th mile tonight?

Im running a Ported Blower with a 6lb Lower with a MAFia set to 7.

15lbs boost on 91 Octane.

that should be fine, with the lower # it is running richer, with a higher # it is leaner, meaning your running richer now than your tune was set at! racing at the Q tonight? sh!t i might be there!!!

yea worry if you see 11.8 to 12.5

Ok cool! Yes I am running at the Q tonight. Just put on my Drag Radials last night!

Now, with these drag radials, can I Launch, or still have to feather into it?

If launch, at what RPM?

You wont know that until you get there and see what the track prep is like....

Rich is safer. The lower the number, the richer the mix. 11.9 is the highest you should ever see, depending on your timing, you might want it lower then that. 11.0 - 11.2 is really safe imo.
