With the New Era the intake is supplying cool air all the time so we get the herky jerkies all the time (at steady low throttle speeds). I like the accelleration with the New Era but the drivability sucks. The dealer told me nothing is wrong but I'm gonna keep trying to find the reason for this! If you get a tune there goes your warranty!

I have been really trying to feel, see and even instigate some of the problems guys here have noted. I cant. I even left out the baffle they sent to eleveate some of the (buffeting) issues some guys where seeing when the fans came on. The design is sound.
I have ported my throttle body after I evaluated the CAI and that helped immensely with the throttle transition from off idle to mid throttle. There is a really nasty lip on the bottom of the throttle body and when ported (CORRECTLY!) it wakes them up and smooths them up. When passing on the highway I get no hesitation now and the thing wont lurch. Throttle inputs are now directly proportional to power output. A professional head porter will have no problem with getting these throttle bodies to deliver a smooth transition of power but if ported incorrectly it will become worse than you ever imagined!
Its a large throttle body and does not need to be hogged out. It just needs to be finessed.
P.S. Have any of you guys who are experiencing problems done a fuse pull to reset your throttle position sensor? Have any of you done an ECU reset? I do both about once a week and it always has positive effects on acceleration and driveability.
