My motor is a fresh build, less then 1500 miles. I put the new LIM gaskets on when I did the job along with all new vacuum hoses and fittings.

I did find a small leak in my cross over pipe due to the crap clamps (I have not put the 2.25" band clamps on yet but will)

I will more then likely pull the supercharger off and Northstar TB and reseal all of that...

Also, the nipple on the TB in the pic goes to my evap. I can pull that line off with the motor running and NO CHANGE!!!! Vacuum doesn't drop, car doesn't sputter, nothing. I remember with my stock throttle body, if that came off the car ran like crap... Wonder if this has something to do with it??? And I wonder why it doesn't change anything with it unplugged?? I'm puzzled...
