You could spend the money on that chip thing then spend the money for the time on the dyno if you would like. Remember you will need to get a base line to compare to so before & after install of the chip on the same car. It also has a lot of claims you would need to monitor such as fuel consumption ect. Under the link I provided earlier on piggybacks & standalones there was a link to Jet performance. You send them the ECU & they will chip it then send it back to you. There a few other companies that offer similar services. Chipped ECU are very limited to what you will gain in return & are generally set to certain parameters with no alterations can be made.
