Hi All,
I Actually started talking about this issue in a different thread, in the 5Star forum, but I figured I'd post it here since it's not directly associated with the previous thread.
Here's the original thread, for reference. https://www.expeditionforum.com/threads/five-star-tuned-2019-ecoboost-expedition.46013/post-446102
So here's the scoop. As many of you know and as you can tell by my signature line, I have quite a few mods, many of which I actually bought from 5Star. So a few weeks ago, I ordered a BullyDog tuner from them, with four tunes, 87 and 91 versions of the daily driver/tow and performance tunes, supposedly adapted for my modifications. So far most things have been great.
However, this last weekend, I took her on a 3.5hr drive each way through the CO mountains, up and over several passes. I started to notice a strange behavior during light acceleration at highway speeds. I was truly worried I wouldn't be able to replicate it very well, but today it happened, again on a highway under light acceleration. I'm currently using the 87 daily driver/tow tune. And to be clear, with 20k miles on this, and nothing else done to it in months, I can sort of only blame the tune. Curious if anyone has seen this. Essentially, when you watch the video, you'll notice the boost gauge freaking out. Hi and low, hi and low, hi and low very rapidly. And I apologize for the music in the background (didn't have time to shut it off while reaching for my phone) but if you turn up the volume, you can hear the blow off valve dropping pressure rapidly as the boost gauge drops.
I'm going to call 5Star and talk to them about it, but i'm curious if anyone else has seen this or has any ideas?
Sorry, link below, not sure when it happened but it appears as though we can't embed youtube now? Only Apple Music? What's that all about?
