I'm looking to purchase a HPP3 part # 30010 that suppose to be for a 2001 LS1 z28/Pon. T/A. Well my engine in my truck is 2000 LS1 Pon. T/A and the HPP3 unit calls for part # 390753, does anyone know if this unit # 30010 will work on my engine ????? The owner of the unit says his z28 is a 2000 with LS1 and it worked fine, unit has been reset to factory. Any help ????
