22 x15 Full Delete Questions ?

[BearsHeavy]

I have recently purchased a 22 Pete 389 with a x15. I am looking to fully delete the truck. I am not sure where to start. I did not find any info on kits sold and when I speak to my mechanic he talks me in circles. I don't understand the difference in removing the EGR system or blocking it off. I am willing to buy a laptop setup that can also be used in the future with any other issues with the truck but I was not sure if the ones I am looking at will do the tune properly. I see one on diesel scanner.com for $2,600 but not sure if this will properly tune the truck after the delete looking for advice and steps to take to get this deleted and tuned personallyby me not a shop I have done many before just not on the big motors mostly ford 6.7 and Cummins ISB med duty if anyone can guide me a lil I'd appreciate it thank you!
