Your car is running really rich, -10 ltft is not good you want it to be as close to 0 as you can get. -10 ltft means the computer is cutting 10 % of fuel
There is a guide to starting hp tuners I would recommend using to get started
Regular cruising its within 0 - -5. Ill see if I can get it dialed in better at WOT
