ok so i tried the vta route, knowing that it wasnt going to run good but went ahead and checked it out. I made my own little plug, didnt take a pic because it looked so ugly. I have no current mods on the car so it was the stock bpv. The first initial revs while sitting still were really loud, i did notice the car idled lower while sitting. Normaly i idle at 750 and while vta it idled at 500. While driving the car was terrible, i didnt hear any popping and backfiring but the shifts were not smooth at all. The stock bpv though was very loud. So all n all the sound was fun but the car hated it.
