Default Link ECU and Injectors

I finally have the Link installed with my GT2554R and other begi setup, but I still have the 1.8 tan top injectors on. I will not have the 550cc injectors before the end of July, and only have used RC 370cc injectors that I can use for now. If I leave the tan top injectors on, I assume that I will have to stay at low boost for now. What adjustments do I need in the base map for the link to stay with these injectors? Also, will it be easier if I instal the 370cc for now, or it would not make too much of a difference?

I am running a link Mk2 ECU in my 1.6l MX-5. I have 330cc injectors and am running about 9 pounds of boost without any fueling issues. I loaded the turbo map, which is also the default map, and then proceeded to perform the coarse and fine tuning. I have a wide band O2 unit to facilitate the 'on the road' tuning. I found that I was able to do most of the tuning in this fashion and then used the Data Log Lab software to tidy up the fuel maps. Therefore I would say that 370 injectors will allow you to run at a higher level of boots than I am, assuming you have everything in place to allow the ECU to auto tune the right levels of fuel and timing for your setup.

Just my 2 cents worth.
