Lee, I have the same issue with my defective rear tires. After Pete's work, I just can't keep them from spinning every single time I drive it!!!!!!

Brett,

It sounds like your really complaining about all that power. Pull a couple of
plug wires!

BLMs at cruise are 116 and 128 at WOT
CONGRATS Lee! It sounds great and I know what you mean with new found power. I'm heading for Nitto NT05Rs to see how they hook up.

Lee,

Sounds like we need to add fuel at idle and lean out cruise. BLMs will always show 128 at WOT because you are now in Open Loop. WB O2 is only way of telling what AFR is at that point.

Isn't 116 a bit on the fat side for cruise?

I thought that you need to remove fuel to get to 128.. I always forget, since I have a program I created that does it automatically I never remember the actual formula without looking at my code... LOL

Dom,
What do you recommend for someone wanting to add WB O2 to their car and do you need to install dual bungs and have dual O2 sensors?
Thanks,
Craig

Thanks Jeff. I thought so and a friend said only 1 side really needed but it seemed you need two because even now with tuning it was found I have a problem on the right side with leak causing lean conditions. When I put my headers back in and install X pipe etc. I thought a good time to have the shop put bungs in even if I plug them for now, but could use when doing the dyno tune with WB O2s. I found one the Innovate system with dual O2s, but very pricey.
