Look past the marketing Sam.
If stock is igniting the air/fuel mixture, there's nothing left to ignite more. You can't half ignite fuel. Weather it be a same spark or a huge spark, the end result is still the same.
Same for multiple sparks, if you've already ignited the mixture, there shouldn't be anything left and there won't be with a proper working system. So in the end all your doing is prematurly wearing out the ignitor.
No one here on this board or ever should have to rev to 10,000rpm. Very few cams work that high. Reving that high in a stock motor isn't possible and is stupid if you try. Also OEM ignition systems still work till 11,000 rpm. Another point to save your money.
Again, you can't re-ignite something, that's already been ignited. There's nothing in the chamber. More so just wearing out the ignitor.
All this is, is a two step launch control. Sam and Wayne don't even use this, or atleast at PITTL Sam I haven't seem you use this. Wayne I know did bother. Practice your launching and you should have a problem.
All it really does is lower your rev limit till you pass a certain speed. (Helps for traction)

Sport Compact enthusiasts will be excited to see MSD’s newest ignition design! The MSD Sport Compact Ignition (SCI) is the ultimate ignition for the high revving smaller displacement engines that are found in late model sport vehicles. At higher rpm, stock inductive ignitions cannot produce full power sparks resulting in a loss of power or even a top end miss.
The new MSD SCI Series Ignitions feature capacitive discharge circuits that are capable of full power sparks at any rpm! Whether you’re idling through traffic or ripping through the gears at 10,000+ rpm, each spark of an SCI Ignition is at full power! High powered sparks mean complete combustion which puts more power to the ground.

There are two models of the MSD SCI Ignition Controls offered; the SCI, PN 6300, and the SCI-L, PN 6320. With these proven ignitions, your sport compact car will get the spark power it needs to outperform the competition on both the street and the track.

The Soft Touch Rev Control will precisely limit the rpm at an adjustable amount for overrev protection and is supplied with a 3,000, 6,000, 7,000 and 8,000 rpm module. This built-in feature also allows you to use an MSD Two Step Module Selector so you can have a holeshot rev limit!

There's plenty to do outside my room but I choose not to!

suhk, what internal mods did you have that supported the MSD ignition? you were still on stock compression, stock internals, stock cams, so what's wrong with the stock ignition system? the only reason you were shooting fire out of your exhaust was because your car was not tuned at all. if you had a apexi vafc you could have retarded the timing on your car to a point so that all that ignited fuel flaming out of your muffler would have combusted in the piston chamber and you could have made alot more power.
