Would be nice to know what Fuel Management System you are using too!

DSMLink? SAFC? EMS? Other?

 

[SlipGear]

None yet. Maybe a SAFC in the future. I figured with the logger and the maft we be ok.

At least a SAFC will be required in order to manage those injectors... Get it as soon as you can!

You will not be able to get a good tune what so ever with just the maft, there just simply is not enough fine adjustments. It will however compensate pretty well for the injectors.

I helped my friend get a base tune on his car with those injectors and an EVO 3 16g. Between just one click to lean it out his AFR's jumped way lean. He is still getting 26mpg though and AFR's driving around still look very good.
