Before anyone buys a chip and has it installed, you should know all the background on this "one size fits all variety"

Chips on turbo vehicles can increase the amount of air entering the engine, by increasing the amount of boost. This leads to great gains, (30 to 60hp in some cases like the Audi biturbo V6). On a NA engine, air can not be increased, all that can be changed is ignition timming and the fuel map.

So they advance the timming to 18 degrees (which can be done for the cost of renting a timing light) and make the fuel mixture alittle rich at wot. The fuel map is nothing more than a programers best guess at what would be good for thousands of productions cars. The reason they can't just tune it specificly for an integra, and have it work great for all integras is every engine is different. Every engine will produce different numbers stock, and every engine responds to modifications differently. So, the most you are ever goign to get out of one of these chips is a 5% increase in HP.. at the very most. In some cases you might even lose HP.

Raising the stock redline is barely of any benifit since your engine is not going to be making any power that high unless you have aftermarket cams. Your valvetrain is also not setup to handle that high reving, and it is eventually going to lead to damage.

For low cost the best bet is to get a v-afc/s-afc and have it tuned wide a wide band O2 sensor and a dyno.
