For those who have changed you plenum. When starting the car in the morning does it seem to idle a little higher than stock, I am currently idling at 1500 on morning start. Also did you have to reset your ecu after the install. What difference did you feel after your install. I am also going to get my timing adjusted by 2 degree would that help.

It might idle a bit high, but it'll come down pretty quick as it warms up. Also, the ECU may need to adjust. You don't need to reset; it'll do it on it's own. Timing advance won't make any difference in this regard.

Thanks just glad things are normal, now just waiting for my z cover to arrive.

As for feel, give it a few days, but you should just have a general feeling that the engine is breathing better and you'll feel better performance above 4500rpm to redline.
