    This product is everything is advertised. I am really happy with this product. I will admit it is kinda difficult to install. Getting everything out is easy, its just a pain how much of a tight fit it is. Overall super happy. its definitely quicker spool up and more power. EGT look like they went down but i don't really keep a close eye on them. I have a 2007 nbs chevy with only performance upgrade is this and a fast 95gph, not deleted. I noticed before I had poor performance in 4th gear, had to give it about 45% or more throttle position to get it to slowly speed up. Now its only around 30% throttle position. (keeping eye on my edge cts2) Don't listen to people that say you don't need this. if you want more performance definitely happy with my purchase and its a fairly cheap part. Just be patient with the install, and having a second person can help but i did it by myself.
