This car was also pulling around 290 load at 24 psi before fixing boost leaks. Then the boost leaks were fixed and it stopped knocking and took some timing. Here is a short pull running 6 degrees at peak torque 11.95AFR and holds 12:1 at 7250rpm's and 15 degrees of timing. In some logs if revved out higher it'll hit 16 degrees of timing.

Its pump gas, sunoco 93 or exxon 93 I'm not sure though. My 1g runs about 6-8 degrees at peak torque and in excess of 20 degrees at 7500rpm's on 25psi and pump gas at 12.6:1 AFR and its moving a LOT of load (400+%). Check your car for boost leaks to 5psi more than you are boosting and make sure your motor isn't flexing causing a pipe to leak under torque.

While we're on the topic, the Dyno Dynamics at "The Shop" in CT has been "adjusted" to read higher... which is ridiculous and sad.
DynoDynamics is a load bearing dyno which uses EXTREMELY precise electronic brakes to measure how hard your wheels overcome the known force of the brake, which is always constant, regardless of age of the unit, air temp, humidity, etc... it's electronic.

The former in-house tuner chose to "adjust" the correction factors to "show" dynojet figures which wasn't very true as the adjustments weren't constant...
i 've seen with my own eyes dynos and tunes with 1.10 cf, 1.15 cf, 1.17 cf even 1.175 cf... the tuner who is the handler of the dyno choses the variables for whatever reasons...
the dyno is 100% accurate and precise IF USED CORRECTLY....
for example you can check my UNCORRECTED numbers in my sig... 309whp @ 22 psi with a catalytic converter and afrs high 10s low 11s... car is a full bolt-ons...
