Why do the revs not drop during shifting.

A very annoying problem, they hang very high even after your foot is off the gas, and the clutch is in. Has it got anything to do with the throttle body's electronic drive by wire thing?

You'd think an electronic throttle control would be crisp and fast, not laggy and shitty.

So I assume it can be "fixed" with some ECU work?

Find someone who knows how to tear apart algorithims and make them friends with another chap who edits PCMs. You'd be in business.

You're best off looking in the Nissan camp because that's where I've seen the best throttle response by wire.

Does this problem have any thing to do with the SC? I am still new to Super chargers? I would think there would be somthing like a blow off valve to relieve the boost built up? I could be way out to lunch here just wondering

Hi,

I'd actually have to say it's probably common between an SS/SC and and SS/NA... I test drove an SS/NA last Friday and found the high Idle to be the same as the SC...

I've test driven an Ion Redline though, and have expirenced no such problems...

there is a bypass valve in the s/c that can relieve boost

I have a RL and have this problem, now I have never driven an SS so I don't know how bad it is, but when I am just casually shifting gears (no forcing, just a nice pace) the rev's maybe drop 100rpm or so, they seem to hang.
