TXsilverado- my experience. when i had my ported fast on my 4.8 for that little time then i swapped to the ls2. i noticed a big seat of pants difference off boost between the two driving. the fast was much more snappier and seemed to just run cleaner. you should feel a nice difference
glad to hear. i already ordered up a 4" 90* rubber elbow from airflow systems
