Hi all.

I just purchase a Supercharger kit from CAPA, wondering any guy here install a charger kit on their H3 3.7 model.
I would like to know would the stock injector be lean out if after tuning ?
What's the best available ECU tuning tools available that suit a hummer ?
Do we need to upgrade the original fuel pump or do we inline with addition fuel pump ?
Possible to post some pic here would be great.
Hope I can get the best setup for this charger.
Thks guys

Mike
