Question for Julio on the Tuning sticky+wb

[Pronto]

Julio, in your Tuning for Alky sticky, you recommend a wb ratio of 11.8-12 and then 11.5-12. I've seen 10.8-9 and 11.1 bandied about lately. That seems to be large gap. I'm going to upgrade to the TT6.0 chip soon and am trying to get a good starting point without being too rich or lean right from the start. I suspect my car wants to be leaner than 10.9 which is what I'm seeing now in 3rd. I know lean is mean but I don't want to too close to the edge.

Are you still recommending that tuning sequence of target boost first, then add timing and then fuel adjustments? I'm achieving my target boost (26lbs) with no knock fine.

Start at 10.5:1 AFR and then move your target up to 10.6, 10.7, etc. As the MPH on the car improves.

I'll redo that sticky.. info is very old. :redface:

So then the 10.9 is about right then?
