Think you nailed it Johan

nah, I've seen them revved harder than that...something else is up, with the TCM file it sounds like.

I'm using the canned Firm TCM tune with no changes. I reset everything when I put this latest tune on.

check for codes?

Checked for codes with the Actron, nothing coming up.

These are the Last Tunes Written. I think they're the right ones. I gotta go to the store, so I'll do a log right now.

Here's a shitty log. Traffic sucks. I thought I was recording a better one on the way home, but when I went to save it, oops, I never hit record. Shit.

Oh, and she's still taking a while to start occasionally. Cranks for like 4-5 seconds and just doesn't want to catch.

Heres a better log. I don't know if it hit WOT. It had just started raining and I kinda lost my nerve.

Guys will the ECU automatically add fuel if it sees a lean condition? Hoping to change the blower pulley this weekend, which will obviously lean out the motor.

I chickened out. Decided to put on the 2.55 instead of the 2.38. Don't want to risk over spinning the blower right now. Maybe in the future.

if your fuel trims are positive at normal part-throttle fueling - which means you're running lean and the ecm is adding fuel to keep the stoich AFR at 14.7, then yes - the ecm will assume you will also be lean at WOT and it will add that same additional amount of fueling at WOT on top of the WOT fueling table...

which is why generally at normal part-throttle fueling, you want your average LTFT's to be at 0 to -3.xxx, so that when you go into WOT, it does not add any additional fuel, so that you can better adjust/predict for what your WOT fueling and AFR will be...

Thanks guys.

It won't be this weekend. Just got a message from Lingenfelter that the pulley is backordered. Maybe next week.
