Not new to diesels, but incredibly new to performance related stuff.I have a 2010 6.4 powerstroke FX4. 90k on the motor. I am very interested in removing the DPF and EGR to help the truck perform better, but am not interested in big HP gains. I thought any tuner you could plug in and just go, but I called a local shop today, and he advised me that after I buy the tuner, I will then have to track down a shop to buy the actual tunes or software and THEN run them in my trucks computer. I have a limited budget and found the Gearbox 4.0 I believe its called and was wondering if that unit comes preloaded with delete tunes or any other brands that come preloaded with delete tunes. That tuner is literally $280 right now brand new. If by some miracle it does come loaded and I just need to literally plug it in and follow the prompts, what else will I need to do beside add the delete pipe under the truck. Thank you all in advance.
