The tune is $490 and im a big boy little guy, if I can rip up $500 when I am extremely mad at someone to prove a point and I can paypal liski money for no damn reason at all I THINK ill be alright spending $490 in hopes that ill see SOME kind of gain… I wont lie to you, I’d kinda be dissapointed with anything less then a 20HP(not20%) however an exhaust and intake which imo would make LESS then a 20hp gain would be FAR FAR more expensive then the price of this tune… I have thought it out, there really is no way to loose.
lousy intake for my car, $400 alone.
