I have Contacted Trifecta. I was told that a tune should be available this summer. Let us hope that statement holds true and that Trifecta is not making promises like Elon Musk. At best the attached could show the performance potential of the tune.
Take a look at Vermont Tuning. I had their tune on my 9-5 for Six years with no issues and he kept tweaking it until is was just right. Unfortunatley you're probably already near the limit for power and torque. At least the last gen Regal had a 300lb/ft limit on the auto trans so regardless of how much power you had the tranny couldnt hold it or stand up to the abuse. So be careful!
