haha I know I know. But I didn't choose the injectors Slowboy Racing did. I sent our guy there the full list of current modifications and he said we needed the 750's (which were no more expensive than the 660's I had planned on buying) so it seemed unlikely that he believed I needed less than that. I have a HUGE turbo! heh I do appreciate it though and had if I have sever problems with idle I will probably EVENTUALLY get a chipped ecu. But I hope I don't have to.

Just to be an idiot: FIC 1500CC injectors can be flashed on the evo ECU to run perfectly and you can run E85 all day long. (E85 uses a LOT of injector)

I thought about being E85 compatable, but it burns up twice as quick I am told. Besides I have a few friends running a mix of it and I might do that if I ever need to. ANYWAY my 750cc run perfect. I have a smooth idle without using idle smoothing factor no problem. I do have a SLIGHT bit of idle surge at startup, I figured that came with big injectors though. If not I need to clean my idle air, or replace my tps.

Ohh how I hate reviving old threads, but since one of my injectors is on the fritz and needs replacement here I am. I just wanted to clarify that we can indeed just use the ECU+ scaling to handle larger injectors and won't need to install an AFPR/Gauge? Looking at FIC 650 or 750s to essentially 'future proof' them.

And before I forget, good job on new release Tom. Now I have to do two firmware updates since I still haven't upgraded to 2.10, lol.

On the DSMs, the 7xx injectors are pushing the limits, but should be ok.

Ok awesome. I found another thread where you had posted some formulas for 550 and 650 for someone else. Makes me think that 650 may be the largest i should go since it'll be +30% over on fuel map with 650 translation.
