don;t do the injectors unless you have a programmer. And you will want to get an AFR gauge to really see if it is helping. I just bought an afr gauge (188 bucks from teamc) and I will see how those 24#ers are doing.

They don;t sell the ones i have, but there are good injecor places out there that sell 4 hole style injectors.

ww.fuelinjectorconnection.com --these guys seem to be cheaper.

 

I have the Hypertech Max Energy tuner. going to be adding the pillar gauges and maybe the bulldog watch dog so I can really monitor my truck.
