GIAC dyno testing of 2008 - 2005 Jetta and Rabbit 2.5 Liter

Dyno results for the 2.5 liter Jetta®/Rabbit® will vary. 93 octane customers will see higher gains over stock performance. Differences in gains between the 2008 and previous years reflect OEM calibration and engine component upgrades. Below we show third gear dyno caparisons of the GIAC performance program to stock, as well as the affect of adding a VF-Engineering Cold Air Intake. Each set of plots were obtained with the same ambient, coolant, intake air and engine temperatures.
