I have a 2000 cummins 4x4. The only thing done to it right now is a diamond eyes 4" to 5" exhaust, and a blue chip injector pump. I'm looking to install a perfromance chip/tuner. I've heard the smarty tuners are really good. I do some towing of campers with my truck. other than that its just normal driving. I am also going to upgrade the injectors this winter. I was thinking about going with 90lbs? any input you guys would have is awesome. Thanks!

 

Go with a SMARTY and 275 RV injectors.
You should see better mileage and will feel real power improvements.

BTW, injectors are rated at hp improvments not in lbs /hr.

 

Is your blue chip pump stock hp or bigger?
If it's stock, your turbo should be ok for enough air. But night get a little hot with injectors and a chip or programmer. If it's bigger then stock, you'll want to be thinking about turbo upgrade with chip and injectors.
I'm a fan of the juice with attitude cause of all the gauges it has as xell as on the fly power changes.

 

its the stock replacement pump from blue chip, not the special x one.

 

I stack Smarty with EZ.....been EZ on it until I put in the BD Converter, VB and Pan I bought.
