ok i need to enrich the fuel air ratio by 10%. i have tuner cat, ho do i go about doing this?

 

Thats a broad question. Where does the fuel table need to be enriched? If you have a speed density car, then you want to increase specific cells on you VE table, or Fuel Table #1. But you didn't say where you need more fuel. Where you do this is going to be some combo of RPM and KPa.

Trick question. the trick answer is change the injector size by 10%.

ok ill try to make it less broad

 

Or increase Fuel Pressure by (1.10^2) percent, or 21% for 10% increase in flow rate.

 

how do change the injector size?

 

I use GME Pro & it is called "injector flow rate for Double fire". it is expressed in lb/hr.

 

now i have found where to change it at but its at .5 how do i raise it by 10%?
