today coming on the freeway, i tried to gas up...i noticed that i couldnt boost more than .5bar or so and my egt kept on going up. i got scared when i saw it at a bit more than 900 celcius so i let off the gas and cruised. it happened all out the sudden. the vacuum on the boost is also a lot higher than normal. it sits just a bit below 0bar. i came home and looked at the obvious, mbc and bov still looks intact. what do you guys think can cause this problem? usually the egt is at 870 or so when you do 3rd gear pulls when the car was working fine. the car was working well until this happened on the freeway.

my car is stage 1...turboback, mr bov, dejon mbc, injectors, fuel pump, and s-afcII tuned. thanks in advance.

the car idles fine and no weird noise is made or anything. also there is no CEL, and i ran an obd2 reader just in case and it also says "no code"

 

Boost leak, or waste gate accuator stuck. Check all your lines.
Is your air box stock, make sure the clips did not come off, could be sucking it to the hood.

Also check the upper IC pipe (where it attaches to the TB) it may have popped off.

 

Check for boost leaks! Make sure you tighten all your intake couplers & clamps. Listen for any weird hissing sounds at idle. How much vacuum do you pull at idle? If you do not have a boost leak then it is most likely some type of wastegate malfunction (highly unlikely).
