I need help with tuning my quadzilla 4K for my truck. Truck has 188/220 cam,103 springs,7x13 injectors, pushrods and studs and t4 manifold but I can’t figure out tunes for my setup it pops at higher rpms and sometimes even shuts the truck off. I have a brand new fass 165 set to 20psi and 15 at wot. Any help will be appreciated.  

I'm going to move this over to the Quadzila forum to give it better coverage of eyes.

please post the tune you are running.  

 

also please give us details as to when the popping is happening?  WOT or light throttle? what is timing at when this happens? how about fueling?
