Swapped them out. Noticed a difference in starting the truck this morning. It seems to pull harder down low as well. Also spools the turbo a bit quicker (at least my impression). Didn't really add much power, just added a good amount of responsivenes and gets you into the power band faster. I'll be dynoing in a couple weeks to get a baseline and will get a baseline with stock and with modded IDM to see the difference.
