upgrading e99 pcm

[iceman_1000000]

I currently am running XLE4 PCM in an early 99. I was looking into trying to find a PMTx to put in as I heard the tunes are better as everybody likes to work with that code the best.

However I also heard that a few years back that may have been the case, but not anymore. Supposedly since then there have been advancements in the e99 XLE4 that will make switching to a PMTx not worth the upgrade.

Is that still true? I'm willing to try a swap out with the PCM only if it will give me better results, but if tunes have improved to make it unecessary I wont bother. I was looking into the Pheonix. Currently I have exhaust, intake, superchips. Looking into possibly an HPOP next. Thanks.
