Boost pressure release Spartan 210 vs 275.

The boost release on the 210 tune is WAY more aggressive than on the 275, at least on my truck. Is that normal?

yeah.. I would say normal, my truck is stock and i can get it to do that so i wouldn't worry.

that would be expected sound releasing 30+ psi of boost when your torque converter locks and you go into overdrive. mine does it on either tune accelerating like that.

I understand what the sound is. I guess my question is, why would the milder tune sound so much more aggressive than the bigger tune?

Could it be that the bigger tune itself affects the rate at which it releases the boost through the turbos?

The way the vgt is set and other factors come in to play. Usually lower tunes run higher boost than higher tunes until a certain point in throttle. So for daily driving and etc your lower tune will run a higher boost, but at WOT and hard throttle runs your higher tune will run higher boost. If you can understand what I am saying

Ah. Makes sense. Thanks for clearing that up. Makes me feel a little better about my truck, I'm new to diesels so I'm still learning the ins and outs.
