Excellent Product to say the least...anybody with the 4th gen firebird *3.8L V6*, this is a great upgrade in power and preformance! There are two stages of power, however Im starting with the STG 1 and the stage one is no joke. After installing this, you do notice a difference @ WOT and general power through the RPMs. Have seen somewhat better gas mileage after, but this was more intended for power. Smooth Install, No Check Engine Lights or Computer Issues! Follow the instructions to the letter and you'll have no issues! (Be Mindful)...when installing this in a firebird be sure to respect the 'clearance' of the hood as it comes very close but does not touch the PCM*...but if your not careful damage could occur! Overall, Very Satisfied!!!!!
