I did 2 runs in 4th gear, and 2 runs in 5th; extra $100 but I needed to compare. I wanted to see how 96 octane would do on Dynojet with 3psi over stock. To be honest it feels a lot faster in +2.5 psi.
Retest next week  |
I would def not run the +3 psi setting again you proved the car was running lean as hell with that 18 AFR at redline , you're lucky you didn't have engine damage . Also if you notice you made the most power on the run with the richest AFR .( this is usually not the case , only when you are running too lean is this true ) . Where is Mike to tell us the 18 AFR is ok lol .
