Hello
I am Looking for an ECM performance tune, for a 2018 Buick LaCrosse V6 with a 9 speed Transmission. Any suggestions?

Thanks

In case you haven't yet discovered, changing the PCM programming for a system that routes through a 9T series trans is fraught with risks. The trans is barely able to survive alongside the torque applied to it already. Pushing it harder without completely re-writing the shift timings, sequences, and associated spark retard/fuel trim is something that even the factory struggles to achieve.

If you find a better scheme that supports more power at the same or better transmission life, you might want to contact GM and Ford, since they will likely pay you handsomely for your magic programming.
