that's right kids, i figured that shit out.
neways, long story short, a55 ignition is rev limited, but low end advanced(why they accelerate so well) but you can avoid this in a number of ways.
gear out so it keeps the a55 in low rpms( the stock ignition, as frustrating and restricted as it is will keep the accelleration pretty good no matter how tall you gear with automatic advancement Via a55 CDI)
replace with aftermarket (HPI)
replace with older CDI (a35)
if you go a35 you will need the a35 flywheel, and the a35cdi box, thats it.
these are still rev limited, but not as bad as the a55, but it kinda sucks cuz you lose alot of lowend, because there's no auto advance, you can just advance it to get to like 10-12k or somthing.
