Seems that I am late in adding something to this post, but anyway... I was wondering being it has been two years since this thread has been discussed. What tune is better now? I am interested in getting the SFR tune or PowerAxel, I was wondering does either tune come with a two-step? What horsepower gains are being achieved on average per tune PA vs SFR? Also what boost does either tune turn it up to? I know I saw someone say 20 for the PA tune, but on a factory intercooler is that safe? What does SFR turn the boost up to on their tune? So basically what is better now? Thanks for your time peeps.
