will it make a difference at this point?

Ok I am getting an ATR exhaust system within a month, with my current mods: full ic pipes, intake, ram air setup(90 degree idle IAT), 190 walbro, and fpr. Will a safc/afc/safc2 be worth it at this point? The exhaust is mandatory as I need a catalytic converter and 3in is as small as Ill go.

So after exhaust would i8t be worth it for me to get a safc/afc? Thanks

I don't know how much you will be able to do tuning wise, I mean with the setup that I read from your profile plus the parts you just mentioned your next step should be some kind of upgraded injectors. If you install the S-AFC chances are you will end up with all of the settings zeroed out or you might be able to get away with some leaning. The way you have to look at it is that it might not be a big tuning factor at this stage but some time down the line you will need bigger injectors and invariably some way to control them. So will tuning your 450's with the S-AFC lead to big power gains? probably not, but will you need it somewhere down the road? yes, if you plan on injectors. I was just wondering why you decided to get a fpr with the 190lph? I have heard of the 255lph overrunning the stock fpr but I haven't heard anything to that degree about the 190... just wondering.

I got the fpr becuase bumping the fuel pressure a bit can extend the injectors a little. Im not looking for HUGE gains Im looking to see if it is a worthwhile mod...

I'm on the stock pump with my t-25 at 16psi and I'm leaning it out 5% with the S-AFC2
