Greetingz all, heres an update on my end:

In the time awaiting Joe from SP for the Pro-M(it seems very difficult to get ahold of him, it's like you get one chance then...), it seems I may have made some in-roads as to my 2000 svt stuttering issue. I tried removing the back-plate on the center post (per WarMongers experiments into this) and after extensive field testing through driving, I can say that "I" wouldnt recommend it for an unmodified svt. Its seems to have a nasty habit of stalling when thrown in neutral without the backplane. Also, my stuttering issue is still quite prevalent. My theory is that by getting rid of the long "tube" that is the center post, you reduce metering-air velocity. Now, heres to the interesting part -- I took out my MAF and placed another backplane on the center post, this time I extended it down a little, so the opening at the bottom is a bit smaller the stock (thus increasing metering-air velocity threotically indicating a little more load then real life [a little more rich?]). I just got back from driving around town at operating temp and I have noticed that my stuttering is not there. Did alot cruising around in 4rth and 5th gear too. I will update again after more field testing (need to make sure stuttering is gone or see where it still exists) but this looks very positive in my case. TtEl.
