This has to be a first -custom tune disappointment

Haha, I know the feeling, my parents live on a steep hill. We always see who can get up without spinning the tires. My mom's expedition holds the 'king of the hill' title The programmer dropped me below my dad's 97 f250. lol The custom tunes take some getting used to.

Anyway... ROtested, you may want to put the truck back to stock, drive an hour or so to let the PCM settle back into a "normal" state and then try the custom tunes again. I've had a few folks do that and it has worked wonders.

If the truck still isn't responding properly with the custom tuning, I'd be happy to get a look at them to see if there's something we either missed or boo-boo'd. We're human... it happens.

Keep me posted.

It's gonna stink (going back to stock) but I'll do it!!! Thanks!

At Bill's request, I returned the truck to stock for a few days (100 + miles) and then reloaded the custom 87 perf tune. Same results, noticeably less performance compared to the canned level 2. I see that Bill tweaked Rustler's custom tune(s) after he expressed similar concerns as mine and that Rustler felt a gain over the previous custom tune. Is that something that might work for me?

It might?
I really don't know what Bill did with rustlers tunes. But I am kinda stumped what's going on with yours?

Greg,

It's very likely that we'll be able to get the same type of improvements. I'm still working on the tunes a little bit for Rustler and clearing a couple minor issues. Once I get those done and confirm they work as intended, I'll update yours as well.

Take care.
