finally!!! another peted innova on the forum.
1. your gear shift isnt happening earlier, the car is accelerating faster.
2. yes, not really a jerk but it does get a big boost from there right till 3500rpm.
3.that would be from the filter. just speak to peter or matthew and theyll tell you how to position the filter so that the noise stops. will you post a pic of your enginebay?
4. you can wash it like normal just dont throw or use high pressure water on the petes box or the ecu. just wipe them with a wet cloth.
