ok i dont have a honda but want some knowledge
I have a 96 cavalier 2.2 (side feed weird a** injectors that i cant change)
so i need an extra injector but i dont really see the point in buying a 500$ and up injector controller! (cnd money here)

so i found this i know the cold start injector works but what I wanna know is if the 16$ switch he's talking about can work on my car,what can it be? http://www.thedodgegarage.com/turbo_extrainj.html

or what else can i use ?

I can safely make around 3 to 5 psi with the stock injectors but i just wanna be safe!
