Scoobyghost Posted January 12, 2017 Share Posted January 12, 2017 PFR7B would be the plug of choice for you. Quote Link to comment Share on other sites More sharing options...
danny wright Posted January 12, 2017 Author Share Posted January 12, 2017 will these not work then as i already got them. Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted January 12, 2017 Share Posted January 12, 2017 Are they the bkr product code? They might work but certainly not the best plug you can use. A local member had to change them out becuase the car just wouldn't boost right with them. Other things to check with your boost issue would be any boost leaks in vac lines. If you recently bought it, check to see if the pill is still in place. Any mods done to it? Quote Link to comment Share on other sites More sharing options...
Tidgy Posted January 12, 2017 Share Posted January 12, 2017 Before you go spending anything, need more info. Has it got mods, has anything changed to cause an issue or was it just fine one day then not the next? Quote Link to comment Share on other sites More sharing options...
danny wright Posted January 12, 2017 Author Share Posted January 12, 2017 it was fine one day then funny the next Quote Link to comment Share on other sites More sharing options...
danny wright Posted January 12, 2017 Author Share Posted January 12, 2017 what is the pill i dnt knw much about these the boot gauge is going a bit wild droping down to 0 bar when changing gears Quote Link to comment Share on other sites More sharing options...
danny wright Posted January 12, 2017 Author Share Posted January 12, 2017 i think its been remapped as its running 260hp Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted January 12, 2017 Share Posted January 12, 2017 It will drop when you change gear. Haven't suggested any money be spent yet. Running through the options. If plugs were going to be changed anyway best to let it be known which plugs to go for. Quote Link to comment Share on other sites More sharing options...
Tidgy Posted January 12, 2017 Share Posted January 12, 2017 unlikley it would be the pill mentioned above. Check all the leads and pipes are connected. going on from that could be a sensor fault Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted January 12, 2017 Share Posted January 12, 2017 Won't be the pill if it's recently started happening unless you've changed the vac pipes. Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted January 12, 2017 Share Posted January 12, 2017 How much fuel was in the tank and did it cut out just after a right hand turn ? As scoobs are notorious for fuel sloshing in the tank and causing boost cut ,when you have under half a tank [emoji6] Search on here for "classic self ecu code check" to see if you've got any codes stored .

stants Posted January 13, 2017 Share Posted January 13, 2017 Sounds like it's either gone in cross threaded or its stripped the threads out Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted January 13, 2017 Share Posted January 13, 2017 Hopefully stants isn't right and your just using the wrong socket and extension combo . As they're a pita to get to and if the thread is fubar it's probably a "remove the cylinder head job " to helicoil the thread . 1 Quote Link to comment Share on other sites More sharing options...
