i have an 01 cummins with an edge with attitude and was wondering what would be a good chip to stack on top of it, any insight would help thanks

 

You don't need to stack anything with what you have. If your running a stock lift pump I would recommend a FASS pump. Then if your looking for more power id get a good set of Injectors.

ok i already have a raptor, and 40hp injectors, but looking to go bigger with those to

 

Edge/Smarty stack is a great combo. But need to get the supporting mods first like Luke said.

 

I would be looking at air in and out of the engine before a stack. At least a BHAF, but a S&B stage 2 or similar would help a lot. Add a 4" turbo back exhaust system and it will be even better. Not a night and day difference, but it will help with everything. Power, mileage, sound, and pave the way for more BOMBs.
