Hi, What variables on the SCT BDX should I be monitoring/logging to ensure the engine is running healthy on any given tune? Thanks!

Last update. I ordered two Unleashed tunes earlier today, asked for an 87 tow tune and a 91 performance tune with shifts that aren't too harsh. Got an email less than 2 hours later that I could cloud sync my tunes. Loaded the 91 tune and drove the same 36 mile route I've been using for testing...

Is it always best to run a 91 tune with 92 gas or is 92 gas close enough to run a 93 tun safely? Don't eat me alive, I'm just asking. I've only used a 91 tune so far, with 92 gas. I'm just curious because I see lots of folks mention running a 93 tune, but I never see anything above 92 gas...

Thanks everyone for your input! Much appreciated. I am going to get an Unleashed tune since I can use the programmer I already have. I will also give 5star a chance to fix my tune, I figure if it turns out to be a nice tune it won't hurt to have the choice between 5star and Unleashed. Though...

Those mpg numbers are stellar for this truck. What region(mostly level roads, hills, mountains, etc) are you driving in? Perhaps my low mpg is due to living in PNW with lots of steep hills?

Do you know if Unleashed will do a tune for the SCT BDX programmer?

I had the 91 tune loaded for over 1000 miles and it did not improve, at all. I have since reflashed, first back to stock for about 300 miles then the SCT pre loaded which I've been running for about 200 miles now. I will reach out to 5star and see what they can do.

I have the stock AT tires, 265/65/R17 I believe. I did not make any tire adjustments or the like with the tuner.

I will admit that I was intrigued by the Livernois tune even before I created an account, from reading all the threads about it. So maybe I came here just for self confirmation or to finish convincing myself I just need to get rid of the SCT and go Livernois. In any case, if anyone running the...

On second thought I guess I could just get some dampers to solve my issues. Or would an engine cover solve more potential issues?

2021 Ranger XLT FX4. SCT BDX with 5star tunes for: 87 daily 87 Perf 91 Perf 93 Perf I tried the 91 Performance tune first, using 92 pump gas. Shifting is SUPER harsh, like ridiculously... a few times I thought I has hit something the shift was so harsh! Then there is the mpg... stock tune...
