no, it really wont be the same price at all, you dont need an avc-r......basic hondata setup for boosted cars is almost 600 bucks, you can get used afc for 200 bucks or less........the most ive seen out of a car with hondata on a stock ls is 290, thats race gas, my car is on pump gas and if on race gas id turn the boost up more and make more power, hondata does let you run no 02 sensors which is a definite bonus, but on pump gas you might get 20 more horses out of it wtih hondata and still be running safely, the good thing is when you go to the track, throw some race gas in it and turn up the boost, but if your looking for the cheapest route to a 13 second or faster car dont buy hondata, if money really isnt an option, get hondata......
