Very impressed with it! It targeting just about 14PSI and has the same spark as my Alky tune from them for my 2010.. needless to say it hauls ass! Thats about a 1.5psi more of desired tip... I think this new SHO is gonna be fun! CAI comes tomorrow. I must say, it appears the remote tunes from LMS are more aggressive on the 2013+ than the 2010-2012 models, which is nice to see.
