incredibly rich for stock, man below 10.0:1 is crazy fat, how much timing are they running from the factory out of curiosity? and how much are you running right now, if you dont mind me asking

I really did like this car! Very nice quality and excellent overall package. Wish I had the 3LZ interior on my own car as it too is a very nice addition.
The car was off the charts rich with the stock calibration. Suprisingly timing was around 25deg tapering off to 23deg with a coolant temp of 190, IAT at 75. 10psi boost. I was expecting the car to have very low timing from the factory.
I ended up setting the air/fuel ratio at 11.5-11.6 and did not modify the main timing table. I did slightly modify the power enrichment vs timing table. No hint of knock and the factory IAT vs timing table remains stock.
The car was allowed to cool off between runs but was brought back up to 190 deg coolant temp for each run in an effort to maintain consistency. (there was no super cool-down money shot)
Overall I think they are very nice #'s for an otherwise stock vehicle

I've seen some of the ZR1 tables posted. The PE is commanded 10.47 in the upper rpms (5600 rpms up) and the timing is 21.5-22 degrees of timing.
