I just put a TSP F35 cam kit in a L76. It idles fine and does not die it also runs fine. Only problem I have is it leans out on take off falls on its face then comes out of it after a sec and takes off. it does not matter what throttle % I give it, it leans out for split second.

What have you done in the tune to correct it? Got a log? Wideband?

Don't mind the Aem Wideband or fuel pressure they weren't hooked to the computer. Wideband goes to 17 18 and then nothing and comes back up to normal on take off doesn't matter what the throttle percent its at. I've added to airflow final min and that's seemed to help a bit. Changed idle timing base to 15 up to 1200 rpms and down to 44 g and coastdown to 17 1200 / 44g. Also added to start up airflow that took care of the idle and dying issues but still left with the hesitating issue off line only.

Is desoot mode still enabled?
It's also got some serious knock too once you get into the throttle.

If you don't post your tune and logs when you have questions you aren't helping yourself.
Desoot mode is enabled still. I will shut that off and see what it does. Can you give me a quick crash course on desoot mode? I have a clearance issues on my header and a broken motor mount I will get them fixed and figure out if that's the issue but I'm thinking that's the knock its picking up

Desoot mode can cause a lean condition upon PE enable.

Thank you for sharing that with me I appreciate it. I turned that off it seems to run better. It didn't correct my issue unfortunately.

post your file.
disable ETC limits and fast torque exit.
maybe look at PE a little sooner also as you have some mad rattle logging, and quite a bit of timing at peak torque
I'm not sure what you meant by rattling log

rattle means detonation or ping generally indicated by excessive knock retard.
your log shows fuel system status going into OPEN LOOP - FAULT at 00.06.25.131
from there fuel trims do nothing narrow bands indicate lean and timing swings erratically. I would start by working out whats happening there before moving forward
That's what I was figuring you meant but wasn't sure. I did realize all my timing tables weren't the same so hopefully that's the erratic timing issue. would you mind pointing me in the right direction on the open loop fuel system? I'm not sure what to do about that.
