doesn't give you a perfect tune....as in ghetto and unsafe?
I just hate seeing people get frustrated when there engine blows a ring land when it could have been prevented had they known...Your engine may run well sure...but how long will it last? What about if you overheat an injector? The 80% margin is there to reduce that risk by a great deal vs running them at 100%.
Will the injectors fail ALL the time at 100% no...but why risk it?
I will stand by my idea of BASIC fuel tuning
Not like the smt6 costs 200X more then the s-afc anyway!
