GIAC Chip power loss.... PLS Help!
I have a 98 1.TQMS GIAC,K&N,UUC,Sebring Exhaust. I have had the chip (thru Dynospotracing) for some time and been very happy with its perfomance gains. I recently installed a 3" custom exhaust with a Sebring muffler at the end (about amonth ago). For past few days the car's performance seems to have changed. Before the engine would pull hard to about over 6000rpm. Now, as soon as I hit 5000rpm the turbo and engine seem to have difficulty pulling it seems like that the chip has "reprogrammed" to cut its boost to 5000rpm. Is this possible? Do I have a worn Bypass valve or Diversion Valve? I popped one of my hoses before but you can here air surging here it doesn't see to be hose problem. Pls. Help! The car runs fine till 5000rpm. I Miss the old GIAC chip power! Any sugestions or tips would help!
