Pretty much my answers have been said , You NEED a custom tune for sure , and the guages are a must, I would honesy check the BPV did you install the kit? I've seen a few guys install the BPV upside down :/. And just for thoughts I made 300 WHP ith my bolt ins and only made 342 WHP on Stillens tune. Custom netted my 412 WHP. And listen to chuck don't mod the SC at all.
