Post Dynoed my car at Dynojet (chart)

Dynoed the car at Dynojet, 622whp = 713hp crank (considering 15% loss)
Used +3PSI on 96 octane.

Did 4 pulls, 2 on 4th gear, 2 on 5th gear.

Should receive Vorsteiner parts next week, I will dyno my car again with +2.5 PSI to see the difference.

Lowered PSI level from 3.0 to 2.5, car feels way faster! I guess 96 octane is not enough for 3PSI, retest next week! Will keep you updated.

What happened on that first run the AFR's went extremely lean and correspondingly the tq and hp dropped off early . There was a ton of variation between the runs too . Did you run the car on the 96 octane and the BMS settings before the dyno ? It appears on the first run the ECU wasn't ready for the extra boost .

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 .

Do you think +0.5 PSI is a big difference?

Apparently so based on the dyno results and you yourself said it feels faster at 2.5 . That's because it is ! That must be the limit of adaptation for you're car with the mods you have .

Very curious to see how the car will do next week, 96 octane with +2.5 PSI. I think I will get a bit less HP but way more torque.

Yeah the torque isn't as high as I would think. I put down 620tq. Torque wins races and feels great . Looking forward to your next dyno

Booking it right now. I changed settings back to 2.5 PSI, and the car feels a lot faster, I'm getting way more torque now. Trying to book for friday, will keep you posted.

Nice. Usually when the car is running lean it should pull a code. Have you pulled any codes?

Not sure about HP numbers, but torque should be a lot better

These SAE corrected numbers? The non corrected numbers are higher than SAE which is what the dyno jet should be corrected to
