Default Running SUPER lean using the W/M kit???

Ok, So I got my A/F gauge installed the other day and tonight I got it all calibrated and working correctly. Then I went out on a test drive. What I saw is REALLY scaring me.

When I am just cruising around my A/F stays around 14.3-14.5 which is pretty much were it should be. However as soon as I get on it and the W/M comes on my A/F drops down into the 10.2-11.2 range!!!! THAT IS LEAN! This can not be good for my engine. I am almost thinking about taking it all out of the car so i don't blow something up! Should I be worried about this? I need your opinions.

Josh

That's rich.

Did you just slap the W/M and not get retuned?

You could prolly do some tweaking and work the timing/boost a bit.

Ok, so if I go in and advance the timing it will fix that problem?

Well the best thing to do would be to log your car. That way you can see what is exactly going on.

Ok, what blocks should I log? I am new to this whole tuning thing so I want to make sure I am doing it right.

The w/m is injecting in the bi-pipes. One on each side. The A/F is getting a reading from the wideband O2 that is installed in the exhaust system.

I'm more or less just thinking that it's misreading the results and not taking the w/m kit into account, but you said it was calibrated to factor that in, right?

You should, as said before timing and boost should be adjusted to get the best results.

You aren't misfiring or pre-igniting are you?

Nope. It runs great! It pulls forever too because of the lower IAT temps.
