Spartan 250 a little sluggish?

[Funyun]

Lately it seems like my truck is a tad more sluggish than usual. Ive been running the spartan 250 on it. I use to like how responsive it was and didnt need to give it a ton of gas to get up and going. Lately it seems like its taking more throttle and boost to get going at the same rate as before. When I step on it though its definitely just as quick as it ever was. Any ideas on what could have maybe changed or happened? I even had someone else drive my truck that rarely gets to just to make sure its not in my head and I was getting used to how the truck drove, but he thought I actually detuned it a bit on him when he drove it.

When is the last time you changed your fuel filter? You dont have any codes I am assuming?

No codes coming up and I changed both the fuel filters about 8k ago and drained my fuel separator a few days ago.

When I replaced my filters at 10k the one on the frame rail had a big piece of goo stuck to the outside of it. You might have got some dirty fuel a while back which clogged up the filter. Almost time for your fuel filter change anyway. Might as well check it out. PTP has good prices on them.
My two cents.

Try re-loading the tune, I think it's recommended every so often due to the adaptive learning on these trucks.

Like stated above, try reloading and see what happens. Then we can go from there.

That was my thought exactly. Seems like my buddy's truck on the 210 tune gets "soft" after a while too. Comes back to life with a reload!

I was actually just recently running the KEM 310 and switched back to my spartan 250 because I like it better as a daily driving tune. This was done probably only 2-3 weeks ago. Even the 310 was feeling a bit sluggish down low which is why I changed back to the 250 because I thought maybe it was just that 310 tune.

Fuel filters, or maybe the air filter needs some attention. I would try a re load just to see if it makes a difference so you can rule that out.

Just ordered some fuel filters and I had just bought a new filter for my S&B intake not too long ago. Im going to change out the filters and do an oil change this week when everything comes in and see how it goes.
