as of right now, i have a td04, and DSM smic....i plan on running anywhere from 6-8 psi. it is going on a stock d16y7. what fuel system upgrades should i do if any? would bigger injectors be sufficient? should i use an FMU? i have never had a boosted car....im a chevy muscle car guy, but i have always loved boost....any imput is welcome...thanks everyone, everything i have read on here has been a big help.

 

You should never use an FMU just like you should never post an Engine management question outside the EM forum

 

The idea of running the FMU would be to run the stock injectors and raise the pressure. I would suggest you read the FAQ in the FI section.
