To some, it's just another complex electronic to fail with no support on the road. My carb (CSU 750 blow-through) cranks on the first turnover (faster than my 15' SRT!!!) and idles, within 5-10 seconds you can drive it. On factory timing however, it's a joke, it takes twenty seconds to crank @ 18-20* while at 30-32* it cranks instantly. Ignition box retards it right back to 18* and it cruises like stock after.
You're fussing about complexity and still running a blow through carb?
I ditched the carb and built a port injection EFI intake for my TT440 more than 10 years ago.
It started on the first revolution of the motor in most cases. The drivability was MUCH better. Carbs can be made to work under boost but you're crutching it here or there. Go EFI and don't look back.
