I seem to have a misfire/sputtering situation occuring @ 3500 rpm, at partial throttle. I don't know if it's sparkplugs and coils, throttlebody issues, or wastegate related. Any helpful response will be greatly appreciated.

Check your plugs first and then look for a boost leak.

what r some of the signs/ symptoms of a wastegate malfunction?

Probably a boost leak. Can you go past 3500rpm? If so, does it continue to sputter? Check your LICP or other obvious spots for a boost leak

with a bad wastgate your car will over boost,i doubt thats your ploblem pull the plugs and check them i would have done that first before i made this thread.....maybe your mas is messed up i would try and clean it...maybe your blow off valve
