Had Black Bear tune my ’11 5.3 today. Couldn’t be more pleased the results and his expertise.

Some of the parameters he tweaked:

• PT & WOT shifting rpm and firmness
• Downshift sensitivity
• Torque converter lock-up timing and firmness
• AFM gear- and load-specific engagement thresholds
• Spark advance
• Tip-in torque limiter(s)
• Tow/Haul switch shifting differentiation settings
• DFCO delay
• Idle speed
• Speed limiter

...All while riding alongside with his trusty laptop. An upstanding gent too.

Highly recommended!
