Default Data log review help

Can someone tell me why I'm not hitting full boost until 5500rpm from these logs? And if they see anything else wrong, besides the little bit of FLKC. Thanks. I was tuned on 93 pump on a mustang dyno around 4 months ago. If you guys need anything else let me know.

My mods are

Blouch 18g 7cm
gimmick turbo inlet
full catless tbe
TurboXS fmic, bov recirculated back to turbo inlet, and their sri with a K&N fiter
Deatschwerks 1000cc injectors
Walbro 255
Grimmspeed TGV deletes and 3port EBCS

Fixed, sorry about that. I guess I forgot to save them after I made them public before posting them.

your WGDC table is terrible... whoever tuned that needs a boot to the face.

Gimmie an hour or so and I'll toss together something for you to try.

Here are two more logs with the revised map that blacksnake provided me with. Spool is 10x better, but fluctuates from 18 down to 14 between 4000-4500. Also I'm leaning out up top which is causing the FBKC I'm assuming.

You're logging the wrong variable for boost. "Manifold relative pressure (psi)" tops out at 18.43. You could be significantly overboosting and wouldn't know (and since you're still maxed out at 18.43@redline, it seems like your boost target is probably significantly higher).

What you want to log is "Manifold relative pressure (corrected) (psi)."

Thank you for pointing that out. Idk how that got unchecked since the logs in the past I've done all had that checked off. I'll post a couple more logs tomorrow with the correct boost.

It seems you may have unchecked boost target as well.

That fluctuating could be a result of your computer trying to correct for the overboosting. It seems like the WGDC dropped pretty sharply. Get another log with the right parameters (same as your first post) and ill make some changes to the map.

Another edit: Your FBKC is probably because you are running lean up top. I will review this issue in the map, but you should start checking for mechanical problems with the car. Like checking the FPRs vac/boost ref hose.

Here are two more logs with correct boost and target boost. The first is a good pull up to 6700rpm, but the second one I guess I lifted around 5800rpm and didn't realize. It looks like I'm still leaning out up top but there is no FBKC in either log. Also it looks like my boost is every where after I spool up. I really appreciate all the help black snake!

Yep, you definitely have a good amount of boost oscillation going on. I'll edit the map when I leave the shop. We should be able to get it perfect in the next 2-3 flashes. Sadly since im not tuning the car myself, I don't want to make huge changes.

Yeah, I understand about not making huge changes to the map at once. I'll have it flashed and logged probably within a half hr of you sending the next revision since I'm free all day.
