So my car has built turbo internals and is streetported however ig gets fuel lag basically and putters every once in a while and i found out it needs and ecu. the stock one works but not to the right specs. is there a cheap way to get it running good like a piggy back or emange system and what kind of tune should i use

also if anyone has an ecu for sale that would be great help
