#Pontiac vibe gt horsepower mods

With better fuel management than the over rich stock unit the difference between the motors is greater. the ECU harness is different and they wouldn't be able to use the included fuel piggyback. I didn't see the article but I doubt it was a stock install. Most of us also like the leather bits inside ,fogs, and the nice sounds a GT makes but those had very little to do with my purchase. Faster, great feeling drivetrain(except clutch), firmer feel (shocks are different), antilock and better feeling brakes, and wheels. Both great vehicles but there is a good reason that poeple pay extra for a GT and it's not the spec sheet. Both cars redline at about the same speed in the lower gears so this comparison is fare. The lower gearing of a GT (25%)more than compansates for the midrange torque difference. A base is slower in any gear and at any speed even when the gt is out of lift. They are very different motors in both power and character. Don't get me wrong, I very much like a base Vibe and they certainly get better gas milage. We're talking from 20% to well over 30% more GT HP in any scenario you choose. You may be a bit closer to a 04 gt but I understand that 04 GTs, like your base, are also a bit underated.

You won't get closer than 30 hp away with your mods compared to a stock GT.

Using 14% driveline loss, the stock GT makes 42 more hp than base before intake and 46 more after.

Chips can help a lot more everywhere else in the power curve.

Slimer, On a base, the best intake adds less than 10 hp (short ram a bit less) and a chip doesn't do much for peak power with an intake because part of how intakes make their increase is by getting the fuel air ratio right at the hp peak.
