chip vs programmer vs usb

[LessThan8]

Hallo everybody! I'm new to the customizing for speed, so i have recently installed cold air intake, and now i would like to increase the hp more.

I have a dyno company down the street and want a chip for my car. How much would these usually run? i have searched and have not found a price.

But also i found online a usb to OBD2 interface. Would this do the same? Write a program to the laptop then to the ecu.

Tunes are generally custom per vehicle especially with one that isn't fresh off the show room floor as no 2 engines wear exactly the same. If you follow some of the discussions on these forums you will see even a custom tune requires recorded logs etc and constant trial and error to get just the right tune. Some companies sell plug and play tune cartrages, but these just plug in generic settings. From what I have read the Sniper Tuning system sounds like the easiest to use at home, but it has a $400 price tag.
