[King T]

Ok this is promising! Seems like the folks at Trifecta Performance are working on a Performance Tune for the Turbo Regal. They are still trying to finalize it and get some of the bugs worked out(stopping the CEL light from coming on) but so far so good

What is said about the tune so far:

For those of you with IDCS, the next paragraph is for you.

When I got closer to my house I decided to try Sport mode. The first time I had the tune installed it seemed to actually get less aggressive compared to Normal when the car first started. I could be wrong but that's what I think I felt. But today.....that was not the case, not in the least. I put it in Sport and laid in the throttle and the car was like "FULL SPEED AHEAD CAPTAIN". Woah! You are now borderline too aggressive is what I thought. At least for everyday driving. Then the favorite part of my drive home, I rolled away from a stop sign, then at about 20mph I planted the throttle, the car kicked down and then it SPUN the tires, with TCS on. This car has NEVER CONSIDERED spinning the tires before. Later tonight I'm going to turn TCS off and see what happens. Basically, I was thrilled. After that I tried Tour, and it responded in the way you would expect, back to the tame Regal I know. Good news, IDCS and the tune are cooperating very well with each other.

I'm also happy to see the transmission not once had any issues or complaints and no check engine light. No apparent problems after an hour of driving. Time will tell if that holds up.
