This is something I am considering doing to my Raptor just based upon the overall positive feedback and knowing it can only help and not hurt. When I initially spoke with GearHeads regarding my current tune, they had mentioned that the tune would need to be adjusted if I were to change to an aftermarket IC, it makes sense and it will allow you to get most out of your tune, keep us posted on your progress
Got my tune in last Monday, 93prx. Drove around a bit that afternoon, and my temps were jumping into the 150s-160s whenever I was driving like I stole it. And would hang out 120s-140s just normal driving.
That was with ambient temps in the low 80s, and intake temps in the mid-upper 80s.
Installed CVF ic Tuesday, and temps were again low 80s outside. Never saw my charge temps get outside of the mid 120s... Maybe 124 or 126 was the highest I saw under the same driving conditions as the day before.
I've driven it all week and went on a road trip over the weekend. Granted, temps have been in the mid to low 70s, I have not seen my charge temps over the 120s, and I often drive it like I stole it.
I would say the advertised 40° reduction is legit. And it is definitely an improvement over the oem ic. I can maybe tell a little difference in the butt dyno when I'm already going 50-60 and get on it, but nothing super noticable.
I'm my opinion, it was a worthwhile Upgrade and the truck probably should come from the factory with a similar upgraded IC.
Now I'm afraid im going to be looking for other performance upgrades, even though it sounds like there's not much more I can squeeze out of it without upgrading the turbos. That being said, I'm super happy with the MPT 93PRX tune. Wish I would have gotten one on my 2017 lariat. It really does completely change how the truck drives. I'll be trying the 91perf tow tune in the next week or 2 and hopefully it will be just as good.
