Symtoms of bad reeds on a turbo?

this is a tough one, bad reeds will show many different issues, some folks will stick true to one single issue being caused from one single time they shcnaged some reeds......its a PITA to tell if a problem is truly related to the reeds. I change reeds every 4-500 miles no matter what, well actually i just change the top reeds no matter what, and will change the lower ones if needed:beer;

i would at least check them out then go from there

I had an SC Apex and had to change the control box out because I got a little moisture in it and started doing some strange things like that. I dried it out and got 1 1/2 rides on it before the same thing happened again. If reeds and everything else is ok, my guess would be the controller. Good luck.

Maybe an air leak ??

Bad reeds are usually indicated by poor idle and crappy 1/4 throttle response on a turbo sled. Once you pull full throttle and the turbo builds boost it becomes less appearant and the pressurized motor runs pretty good.

In the past I have had similar problems like the ones you described but they have been the result of an air leak. I would check to make sure the air box is still connected to the throttle bodies, make sure Pipe and Y-pipe do not have splits or tears and check to make sure your connections are all tight. It could be a split in the factory weld on the pipe and it may not exhibit any conditions until the split in the pipe opens up under full throttle and boost conditions. When that happens the control box, turbo and motor all freak out.

good luck and good hunting. db

Check your boots underneath where oil injection spigot is, seen quite a few 1000 turbos split there, usually the PTO side.
