Hello all!! First Post here. Utilized the site quite a bit researching before tuning my Impala so I thought I could give back with a quick review.

Trifecta Tune went on a special for Black Friday and I pulled the trigger this included free shipping on the cable.
Flash Code was available in my account that night
Cable came in 7 days via US Mail and included two nice Trifecta stickers
PCM /Cable port access is super accessible on these Impalas
Install took less than 15 minutes including flashing the PCM ( I would say some computer "savyness" is required )
Results are wellllllll......... Holy Shit
The shear pleasure of the pedal response alone is 100% worth every penny.
