I have similar mods and made 347 awhp on a dynojet at 24psi. I do not think my tune is bad so I am not sure why I got those numbers. Some people think they are low others think they are fine for pump. A boost leak will give you higher than usual loads so I do not think I have a boost leak. My loads seem to be fine. Here is a thread that shows some plot of logs. It also shows the Load. Click here to see -->> https://www.evolutionm.net/forums/ec...k-my-mods.html

 

Have the car checked, numbers are in my sig and I had Kelford 272's, Stock IM/Head/Motor/ECU, good luck. I actually know of two other people that have made over 420whp on 24psi so you got something wrong there.

 

What turbo? Do you know what is your airflow (Hz) at 24 psi?

 

Is that for the OP or me? either way, turbo is the same as the OP and idk the Hz
