13 to 15 psi

[OnlyNeed4]

I by no means want this to be a ''bench racing'' thread, but i ran 13.6 with 13psi a few weeks back and finally added a pump(along with a ported 02) and planning on running 15 psi, (maybe more if the fuels there) but im just wondering if 2psi is noticable or not since i've yet to turn it up. (i wanna beat my friends 5.0 that ran 13.2, im hoping)

You will notice a difference but you are not going to beat a car that goes 13.2 at least I don't think you will and I'm not being rude I'm just letting you know. If you finish your fuel system and turn the boost up to 20 then you should or atleast be really close.
