I've got all the materials I need, I just want to know if this would really help.

If the EFI is just filthy, I think this will solve your problem. Ive repaired thousands of cars and hundreds of them had the same filthy EFI problem and it worked for those cars. Many of those cars have major rough idling/idle drop/vibration problems, and we dont usually open up the whole EFI unit and the ECU or send the EFI for major overhaul unless it shows up in the diag test or from the engine trouble indicator lamp and often times the problems are very obvious that we just change the parts.
Just be easy on the revs while spraying the chemicals because too much can damage the turbos.
