is it possible to run a vafc to get ur turbo car to run the right air fuel ratio on stock injectors or is it necessary to get bigger injectors

 

yes, you can used the vafc to run a turbo but you still need bigger injectors!!!. What year of car do you have?Unless you live in CA, i will just run a chipped ECU.

check this link if you're still interested in running the afc hack.

get a minimum of 450's or 390's. if you try to use stock injectors.. it will blow up

 

dont use the vafc, get a chipped p28 and dsm 450s and run that instead.

 

Injectors will only flow a set amount of fuel based on its size, so if you are running alot of boost and allowing more air in than the injectors can flow fuel to match you will run lean and damage your engine quick and easy. Also, injectors arent supposed to be pushed over about 85% of their max flow capability since it could cause them to inject sparatically.

So, short answer: depends on the amount of air you are flowing. 9 times out of 10 you will need larger injectors for a turbo setup.
