Random Misfire

[GT2FAST]

I have a 2000 audi s4 with ko4s running at 15 pounds of boost i was getting a misfire in cyl 5 i changed all the plugs and coils but now once in while my car comes up with random misfire. The car will break up for like 30 sec but goes back to running fine again for a while like a week or two then it happens again i dont know what to do .

check ignition control modules on top of airbox. what kind of plugs are you using ?

[GT2FAST]

bosch platinum 4 and how do i go about checking the icu's i was wondering if its just a computer programing problem cause today when i was working on my launches the car loss power and received no boost but it didnt do it again. its weird im wondering if its just a tuning problem.
