How many of you are happy with the new plastic intake manifolds that you have installed? I heard some are having trouble with air/fuel ratios, but no one stated how built the PT was. It would seem that resetting the PCM would correct the problems, but there may be more to it.Has anyone checked the conductivity of the manifold, or added a ground wire to the throttle body? I was considering purchasing the plastic manifold, but wanted to do my home work first. Also if you remove the aluminum manifold it would be an oportune time to upgrade to the 04 injectors (if you have an 03 GT). There are also upgraded intercoolers available, one of which requires no modifications and is bolt in, anyone try the combination?

The PCM will be able to adjust for any AF ratio issues. That is what it does. Don't just drop in the bigger injectors withoug doing the Stage 1 upgrade. Your '03 PCM is programmed for the injector size/flow rate that it came with.
