Update:
Injector kit bolted straight up, no mucking about, no grinding OR relocating any hoses as such. After bolting up all the parts, went into WARI and adjusted my injector scaling & voltage offset table. Fired up the car, started first go on E85 (it never did before with the Five-O Side feeds).
I am very impressed, dicked around with the VE table and got them to idle at 15.7 AFR (gasoline scale). Car idled without any farts & pops, etc. I must say new age injectors are just wonderful.. with low pulse widths and great spray pattern - it makes a world of a difference. To be honest, I don't think I've heard my car idle that nice - even when stock!
I didn't get much of a chance to do any tuning as I threw out my back at the gym.. been in loads of pain, however will be doing some touch ups tonight after work..
I CAN'T WAIT
