| sorry it too so long, just been busy and lazy. this was un-tuned and this is tuned on a mustang dyno. 


while watching Ash tune a car recently that had the same issue of boost dropping off at higher RPMS, Ash said it was because his greddy SMIC restrict airflow and it starts to starve the engine. anyone else have issues like this with Greddy's?
