Hallo,

can soneone tell me the pro's and con's of the differens methods to feed more fuel under boost.

1. using a fuel pressure regulator (fmu) to rise the fuel pressure
2. using a map hack and bigger injectors
3. using a ecu that can read boost and use bigger injectors
4. use the stock ecu, install a map hack so that the ecu don't see boost and then install a secondary injector (a big one) before the throttle body controlled by a sperate ecu that feeds fuel to this injector under boost.

method number 4 is used at the moment but i think its not optimal... i know a totaly different ecu is the best, but its also the expensive way... i want a good compromise.

Thanks
malte.

 

does nobody has an answer to this question? what are you guys running?

 

Send a message to Search, I think he might be able to help you out.

 

Method 3 is the only way to properly doing it. Everything else is just a hack.

If money is a concern, use uberdata and do lots of reading on pgmfi.org.

And a search wouldn't hurt either.
