Bought a 05 cummins 190k miles on the engine bone stock no tuner, has a stage 1 ATS trans. Should i worry about the stock enginw at all?? What should i take it to the shop and have done to the enigine??

 

i wouldnt be worried about the engine, but maybe the tranny. it should be fine if the truck is stock. dont have anything done to the engine, just check your 4th injector line bracket every now and then and make sure its tight. i would add better fuel filtration, this is a nice kit.
