hello everybody i just picked up my 94 rx7 and i am having trouble trying to get the car to make power. its popping and sputtering and also building to much boost. i am guessing the wastegate is stuck? car has been sitting for a while but now starts right up everytime with minimal smoke. maybe a lil blue smoke. when i am driving down the road the twin turbos are loud and hit up to 15 pounds but sputters out pretty bad. just wondered if any body could help me out a lil cuz i checked vacum hoses and all clamps and everything seems tight and connected. mods are exhaust, intercooler, intakes. the down pipe is stock tho. also everything past a quarter throttle is pretty rough? pleease help

 

i fixed it! lines coming of the wastegate were unhooked from the turbo causing boost spike
