[QUOTE="ridge68, post: 14078278, member: 160571"] Yea...factory gauge. Never really thought of that. Only had the car since December 30th of last year, unfortunately I really couldn't get into the throttle fully when it was completely stock because it was so cold and unusually snowy this winter in Virginia. I don't think I was able to get a full boost run while it was stock for reference because of the weather...damn...I was too busy trying to keep it on the road to look at the gauge if you know what I mean I was thinking maybe some belt slippage, I used to have an auxiliary pulley on my 03 Terminator to increase belt wrap around the blower pulley. I went with the VMP setup with the 90mm idler instead of getting an auxiliary pulley for belt wrap. Justin at VMP says in his forums the auxiliary pulley isn't necessary...didn't make a difference...but I'm wondering... [/QUOTE]
