i had my supra down for 2 months to rewire the harness and add a few parts i had ordered of course taking my sweet ass time on doing so.after 2 months put the ic piping,hoses,etc before start up,so then moment comes for start up.couple of times it takes me to start the car but then it starts got it to idle good.took it for a run but im hitting fuel cut at 4000rpms and i spike and hit 16.5 psi but i only have a .5 bar so its a max of 14.5psi if im not mistaken..wtf.i had taken the down pipe off a while back to get the wb bung welded on,but when i put it back on with new gasketsont the wg it doesnt seem to seal right because i can feel exhaust pressure coming through the gaskets.i did a powerbrake and im not building any boost,so i have to do a boost leak test but im pretty sure all my t bolt clamps are on good.
1)Could the exhaust leak on the wastegate cause it from building pressure?..i mean the boost pressure goes up when im getting on it but not while powerbreaking
