I want to do some more mods to the car, but when I had it at the dyno they said at max hp I was starting to run lean. I was wondering if I can jump up my injectors without changing computer program. If not any idea how much it will cost to do this? What I would like to do is get the car up to 400 rwhp and I was hoping to accomplish this with headers and y-pipe, 1.6 RR's, 52mm throttle body. Not sure if that will get me there or not. Any help would be greatly appreciated. I am not sure what I need for the computer or who to go to for the program. Thanks

 

You can run a FMU. i dont think powerdyne uses these with there setup. A 1:2 ratio should be enough with a 45 base pressure
