no it shouldnt be. there arent any EGR passages in the intake manifold. just in the upper plenum. might be the DPFE sensor.1GtUnV said:Ok, also would the P code that reads "Egr flow excessive at idle" be caused by the PI intake?
1GtUnV said:I put a PI intake on my car back in the fall, and ive been reading up lately on the PI intake and many people/places are saying i HAVE to have the PI heads. Is this true, and how easy/how much would it be to swap those out if i must put them on?
streetstang03 said:do the head swap and add some VT stage I cams. you might as well do the cam swap while you have the motor apart.
do some research at www.modulardepot.com or www.modularpowerhouse.com
if your gonna take the time to swap the heads, vt stage 1 is a good cam to go with...get some springs too while your in there. maybe even go with a ported and polished pi head set if you can afford it! i'd estimate a p&p'd head with vt stage 1 at another 40-50 hp. definately worth it.
