I am getting ready to get some injectors and i am debating on whether to get 850cc or 1000cc. The price difference is only 10$ so i will be kicking my self if i run out of injector. I will be running e85 but, that really doesnt matter on this subject. I have had a friend make 500+whp with a walbro and 850cc injectors but, he wasnt maxing the injectors out. Can a walbro push 1000cc injectors to the limit. The only reason why i am hesitant on buying 1000cc injectors is because i am rom tuning with resistors and am worried about idle and low throttle driveability because the injectors are so big. The only reason i want the 1000cc over the 850cc is to help keep the duty cycle down when i'm not in boost.

Anybody tuning 1000cc injectors with resistors please chime in with your opinion on being able to control them.

What is the biggest injector a walbro can pust to the limit?
