Flashpaq 1842 on stock 04 6oh?
 

Hey guys, new to this site and first post ever. Ive played with a few 6.0's same year and watched a few buddies add, delete, make and break theirs but just bought my own about a month ago. Just replaced injectors, but everything is stock. My Pop's has a 2015 6.7l and he just handed me down his Superchips Flashpaq 1842 that he had been running. Plugged it in and immediately installed the Performance tune to test. Woah. Definite power gains(smoked my tires and pipe right out the drive!). I wanted some input on this programmer and is anyone else running this one with these tunnes? I switched over to the Fuel Economy tune and noticed a weird RPM jump after an interstate ride about an hour away so Im back to switching between performance and stock. Thanks!
