Hate to break it to you, but unless you pull timing out over 100kpa then you'll blow your engine. An AFC Neo won't help with that. The stock ECU won't have any mapping over 100kpa because on an NA engine that is the absolute highest air pressure you will ever see. So when you hit 100kpa your timing and fuel calcs will not change.
Word of advice:
NEVER TURBO-CHARGE A CAR UNLESS YOU CAN TUNE TIMING. EVER. PERIOD. FULL-STOP. END OF STORY.
As for the stock fuel requirements at 7psi I'm running about 60-70% duty and 170hp on my 320cc injectors so the stock injectors, which are 240cc if memory serves me, will not handle much boost at all. For 200hp I'd go for at least 350cc.
