whats your vacuum at idle?
no offence but in that first vid your car sounds gutless, like you have a boost leak?
What boost are you running?
Tbh I'm using a fcd with an fcon, I cannot run without a fcd as I was hitting fuel cut at 7psi purely because of the airflow from mods, it could be just that for you too, although I don't know much bout the lex 550 mod i would think it should push fuel cut up some?
Though it didn't sound healthy, it still sounds damn good mate
