LS3 crate engine - seems like low power at part throttle
Background. LS3/6L80e combo into a Jeep JK. It's been running for 2 years flawlessly. Unfortunately I wasn't smart enough to do some data logging while it was running fine to compare.
It just feels like the engine has low power between off-idle and 2,000 RPMs at part throttle. WOT operation seems to be unaffected.
I opened up the scanner this morning and drove it locally to collect this data. Two things that I saw. First, the IAT can spike pretty good (although I'm in Phoenix and it was in the 90s this morning when I did the test. Second, I don't see any information on fuel injector pulse width.
No MIL light, and no DTC codes are shown.
Attached is the log file.
Any thoughts, or what I should try next to narrow down the issue? Thanks in advance for any help.
