hey sorry just looking logs now, admittedly Im not the best for this but I'll see what I can look at.
Also what turbo do you have? what boost controller and how is it plummed?
both datalogs Ipick up the same thing: AFR looks okay, HPFP pressure good, but you ping 5.95 KR at WOT which is alarming does not not look like fuel cut as much as everything is being pulled because engine knocked.

are you hearing any noises? I'd be doing a compression test personally
@Enki or @Easter Bunny may have some more insight

His other thread is the one you replied to. He was sending injectors for cleaning because of low compression on cylinder #3. Can merge them probably.

I posted a new one becuase this one has tons of cluttery guesses and unrelated stuff. I learned alot about tuning and turbo car since I first posted this question. I sent my injectors off. Im running a reman factory turbo with factory boost controller. Id like to keep all discussion on the new thread. Thanks.
