Wow so you would take a stock bottom end car with just a piggy back system that doesnt touch timing or even regulate 780cc injectors properly to 20psi and feel safe? The Enthalpy tune which I hate sr owners do it all the time its tuned for the maf, the injectors and what boost you are at and even adjust timing and able to move up rev limit and remove factory speed limiter with out a standLONE. What you miss read what is the a/f are fine until it breaks up under boost is around 11.5 until it breaks up thats when it hits 14+, its not like nissan has hondata...but i guess all I have is crap on my car...lol
