Then the pipe the y's together that goes tot he inercooler popped off and I lost all power and the car started surging at idle and dieing. So I pulled over and put the hose back on and WOW OMG HUGE again in power were talkin puch it at 20 and the tires squeel power0-60 in 4 seconds power.... Then I get home and 30 min later I goto show my nieghbor about the power gain and... back to being slow... What gives?
