chips
Has any one had success with a performance chip if so what brand. If not what else should i do to add power I've all ready added intake, exhaust and performance clutch what next.

No. They all work on the basis of convincing the ECU that the intake charge is colder than it is and therefore make the ECU add more fuel. More fuel does not equal more power. FCs run pig rich as it is, so adding more fuel just makes it worse. So basically, they're a ripoff. If you're looking for some tune-ability while still retainingt the stock ECU, RTek is the way to go. It's a tuneable chip that allows you to change fuel and timing of the stock ECU. They have a section on the ECU section of this site, check them out.

No, they do not. In fact they're not even a "chip" (integrated circuit) but simply a 2 cent resistor in a fancy case. The theory is that by putting this resistor in series with the IAT (Intake Air Temperature) sensor you can fool the car into adding more fuel by making the intake seem colder then it really is. In reality we all know that more fuel is not equal to more power and by messing with the IAT sensor the car will run too rich and lose power. Also the price is a total ripoff considering that anyone could go out and buy the same resistor for less then 5 cents.

Are you n/a or turbo?
If you're n/a, you've pretty much done all you can do. You could get an SAFC to lean out the A/F misture and gain some power. If you want to get serious, you could rebuild your motor and do some porting while you're in there. For turbos, a simple boost controller can make a considerable difference, just be careful not to get too crazy with it and end up blowing your motor.
