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
