Well, what you have now is
Can you tell me specifically what chip or tuner you are talking about? You are asking to get 500 hp out of a 177 hp stock engine. Thats an increase of 323 hp or almost a 282% increase. I cannot imagine anything including chips or tuners that simply modify fuel or ignition can come close to a 282% increase in horsepower.
I did notice this though while snooping around.
This easy to use software allows for end-user calibration of the PERFECT Engine Control Module. The navigatable dashboard displays pertinent engine readings such as RPM, TPS, MAP, Coolant temp, etc. The various calibration screens - such as Idle, Fuel and Spark allow for easy user adjustment of spark advance, A/F ratios and other strategies throughout the RPM range. The PERFECTION software gives the end-user complete programming control to modify the ECM to accommodate for any engine modifications such as valve train changes, exhaust, timing or heads.
Performance ChipsThis leads us to our discussion of performance chips. Now that we understand a little bit about how the control algorithms in the ECU work, we can understand what performance-chip makers do to get more power out of the engine.
Performance chips are made by aftermarket companies, and are used to boost engine power. There is a chip in the ECU that holds all of the lookup tables; the performance chip replaces this chip. The tables in the performance chip will contain values that result in higher fuel rates during certain driving conditions. For instance, they may supply more fuel at full throttle at every engine speed. They may also change the spark timing (there are lookup tables for that, too). Since the performance-chip makers are not as concerned with issues like reliability, mileage and emissions controls as the carmakers are, they use more aggressive settings in the fuel maps of their performance chips.
