Should I use 450cc injectors and run the vafc hack or use 450cc injectors with vafc along with a 4:1 fmu?

 

hondata

 

Using both, you might run into some pretty rich fueling issues, especially top end. I Suggest one or the other.
Except, I just read the title again, VAFC hack is only Technically good up to 11 psi cause that's all the MAP can take.
So FMU might be better. Tuning might be a bitch with both.

 

proper tuning (standalone)

Jeff-

 

450's and standalone

 

you guys are ****. he didn't ask "should I get a hondata?"...
The afc hack without an fmu is better. Besides, you'd need an inline pump to run the 4:1 fmu and 450's, (that would be around 80-90psi atleast).

 

lol...yea i would get a hondata, but i dont have the money right now. I'm obd2 i have to convert to obd1 so hondata gonna cost me a grand which is too much.

 

If you want power do it right...unless you have the money to rebuild.

 

rx7 550's and the vafc hack... ((the 550s will allow you to run higher boost -- even greater map cut to compensate for even larger (makes sense if you understand the theory behind the hack) ))

 

i agree with the hack and 550 injectors, it will let you run the higher boost with the map cut. im suprised someone else uses the rx7 550's
