upgrading e99 pcm

[iceman_1000000]

Then assuming that I go with the Pheonix chip I could put in a NVKx etc then still get the PMTx shifting progam? Do you find the shifting that much better than if I stayed with the XLE4 I have now? I have been fine with it but then again I haven't driven many others to compare it to.

Also just to clarify if I get the Pheonix then add in a Terminator T500 would I need to have the chip reburned, does an upgraded HPOP make that much difference?

Thanks again for all your help.
