Wanting more
 

I want more out of my 01 cummins. It has 4" magniflow exhaust and knN filter.Can i turn the turbo up in anyway or add more fuel? If not can i add a larger turbo without hurting anything. My turbo seems to pull harder at times also. Is that normal? Thanks

theres lots of programmers u can just plug in a get lots of power. Smarty, Edge juice w/attitude (for gagues and all that included), etc... some say the smarty doesn't fuel on top very well alone, so just do some research and choose what u want from the search's...

adding a larger turbo wont do much on a stock truck, you need fuel to turn a turbo. the most common is the smarty you get 9 different levels of fuel or added timing but you dont have in cab adjustability but again telling how far are you wanting to go with the truck will help suggest mods? also welcome to the site if you fill in your sig it'll help alot so we know what truck were dealing with.
