im going to turbo my b16 and im using h22 injectors, i have a friend that can street tune my car by adding a program in my ecu to make it run safe and think that the injectors are stock. the question i have is he said that i wont take out my vafc. i was wondering if this was true or not. he said that if i use the vafc that it will make that car not run right even if every thing is set at 0 on the vafc. he told me that the vafc would mess up the fuel map that the program set in the ecu. any info would be great.

 

take the vafc out. once you have a chipped ecu you dont need it anymore. sell the damn thing

 

i hope you're using a garbage FMU with those prelude injectors, otherwise you'll max those out quickly adding even a small turbo
