Can I drop 550cc w/ no AFC and expect ECU to tune my car ?

No.





If you do anything else at least get a FPR and lower it maybe 1-2psi lower than stock. That should do you untill you can buy an AFC or something to tune with. Also dont expect to make alot of power with something runing that rich, and expect poor gas mileage.
 
the 550s will make your car run 20 percent more rich due to the 20 percent more fuel they dump, u can install a 2g mas setup that makes it run 20 percent leaner which will equal each other out, youll want that later down the road but be better to get another safc for now, thats your best bet. my car wouldnt even start when i tryed running 550s with stock car. ur going to need the safc good luck

If you are lucky, they will equal. There are just too many variables. An AFC is really needed.

The 2g MAS actually is more than 20 percent leaner. It won't run right.

You need a SAFC at the least.
 
it will run alright, not 100 percent perfect but alot better then just installing 550s with nothing else. i once installed 550s and 2g mas at the same time when it was stock and it drove the same after the installs. point is u cant install 550s alone, either 2g mas or safc with it
 
LOL wow i feel dump, sorry didnt notice that, i found my self always assuming 1gs, ever thing i said goes for 1gs not this guy or other 2gs. either way u still cant install the 550s and have it run ok
