    What do you mean by it has a working EGT gauge? An aftermarket gauge has nothing to do with the issue - You need to have that CEL cleared and if your sensor (not gauge) is still in the UP without a cat it needs to be removed. You can disable the CEL in the map (or your tuner) or you can do the resistor mod.

    What is going on with the other CEL regarding the radiator fans?

    You need a correct tune for the boost control system without the MBC. Do you have a DP? If not you can use a stage I map or the stock map, if so try a stage II map, or go get it retuned correctly. What kind of EBCS do you mean it has (do you mean the stock boost control solenoid)? If you have like a grimmspeed EBCS that takes a different map/tune.

    These are all things that have to be taken care of ASAP - it may or may not completely fix your issue but we won't know until you get caught up.

    there is no cel light on when the car is running the only time i get it is around 4-5k and it will flash 3 times and go off and when i go to check the codes theres nothing there. and it has a blitz ebc. i will hopefully be ordering the cobb accessport shortly and going to go stage 2 tune but until then i will just stay out of boost as much as possible

    Consider just getting a tactrix cable and doing an internet tune like XPT - it will be better and cheaper.

    Remove the Blitz thing and sell it. If you want an EBCS get a grimmspeed and get a correct map for it. I thought you meant the stock BCS this whole time. You can see if that makes things better temporarily, or if you are still overboosting just run the line from the compressor housing straight to the wastegate actuator - that will limit you to around 8-9 psi until you get a tune or a map, and should be much safer.

    UTEC is a good piece, but harder to find a tuner compared to Cobb and Opensource. You could just keep that and the other pieces and get a protune - let them decide if they want to use the MBC etc.
