Yeah, I'm pretty sure you wouldn't. But you probably would get better gas mileage.

Anyway, put in a fuel pressure gauge and look at it as you come out of the last turn before your problematic straight. You'll probably see little or no fuel pressure. It then takes from there to your hesitation spot for the fuel lines and float to run out of fuel and then the engine goes dead. Meanwhile the gas sloshes back because you are now going straight and the pressure rebuilds and refills the float, and then you have your engine back. Happens to me on left hand turns if I run less than five gallons in the stock tank.

I've always used stock coils and never had one go bad. I've been told by people that know more than me that the stock 12a ignition is more than adequate for stock engines. Now a turbo motor at 9000+ is a different story.
