Just done all the deletes on my motor including throttle Valve Delete, got the efi on but not if I put my foot in it just a little my be 2k rims it's like it looses power for a split second everytime it shifts,like it's hiccuping before every gear? What could cause this? Is it defueling? Any help is appreciated, new to all of this

2009's are notorious for that. Either tune the tcm or get used to it.

I put some different tunes on it last night that my tuner sent me and it seemed to fix the issue, but I'm still going to get my tcm tuned

Who did you get your tunes from? I recently purchased an 09 6.7l and I'm looking at getting EFI
