I posted about a week ago in the engine/turbo/drivetrain forum about my low karman readings. People with similar mods to mine are posting 1850-1900 hz and I have barely seen over 1700 hz. My question is do you guys think it could be my intake? If so then would the flash greatly help my situation? Up to this point I have only tuned with my wideband and S-AFC. I still plan on getting a mail-in flash to eliminate my boost and fuel cut, but I'd like to get a diagnoses on my problem of not flowing as much air as I should before I do anything else.

 

I would need to log some data on your car in order to give you any inteligent answer

 

well i figured out what it is. i guess i've never noticed before, but i have some serious boost taper. I have my hallman mbc set at 20 psi. right now and noticed today after doing some logging that it starts tapering at 6200 rpm and goes to 15 psi. at 7000 rpm.

 

Sounds like a boost leak
