H1 performance enhancements
Has anyone had success with performance enhancers for the H1, such as this one:
HUMMER H1 GF Peformance Chip
What can I add to the 2002 6.5L TD (without going to a conversion) that will realistically add torque/HP without risking damage to any component of the drivetrain?
How do expense (best bang for the buck) and expertise in installation effect ones' decision about any of these add-ons???
