slow rpm drop, how do you deal with it?

Hi everyone,

I've done the copper pipe mod to mt 2003 GT to fix the rpm drop which works pretty well once the car is warm. The problem is that it's cold here now in Chicago and until the car warms up the revs drop incredibly quick when it's cold, it gets annoying after a while.

I was just wondering how everyone deals with this? I'm thinking of just taking the cap out for the winter. Those of you that do not use the copper pipe cap mod do you wait for the revs to drop between shifts or do you just let the clutch slip out and bring the revs down for quicker shifts?

Thanks for any advice with this annoying issue.

You could make a couple of plugs... just make the hole slightly larger and test it until it works to your satisfaction.

its in the tune, you need a xcal2 or a predator to fix it.

Yeah, it looks like a tuner or chip are going to be the only way to eliminate the problem. The best deal I can find is the SCT chip for $280.00, any other suggestions?

Thanks.

First, anytime you limit the ability of a part to do its job you are likely to have problems like this. Restricting air to the AIC limits ability to do its job, which is control the idle. The right way to do it, is to adjust the dashpot settings in the EEC wich controls the rate at which the rpms drop. The problem is that this parameter is not available in the handheld tuners that I know of. So ask them to set it when they set up your initial tune.
