400 BHP is a bit much for 550's unless you use them with a FPR. I'm currently at over 400 with RCM 550's and a FPR, they were at their limit at 390 without the FPR.
550cc injectors are top feed, how did you fit them on your V3 Matt? i know you will need to convert your fuel rails to top feed so which ones have you used?
I have a fpr installed along with parallel fuel mod. I will purchase the 550cc. Does anyone no where i can get an adapter kit for v2 injectors for v1 inlet and rails. Cheers
