No you are not on crack. There are other ways to trigger. Some company's use a MAF/MAP varible controller. Snow Performance has this alternative to boost pressure. They also have boost pressure varible controller. But, boost pressure trigger is the easiest way I can think of to trigger. It takes a lot of the guess work out. Plus the time when you need alky/meth is under boost with advanced timing, and higher boost. You car when tuned right should only need it when on boost. When cruising off throttle, or partial throttle in vacumm, or light boost <6 lbs you shouldn't need it. Your car will be tuned like normal under these engine loads. But once you hit a certain boost level and the alky/ system turns on your tuner should start to advance timing on your timing map as pressure increases. He will also start to take fuel away to make the AFR's right with the alky injection. You can look around at other manufactures and see if they use some sort of MAF system also, but boost is easy, and easy to tune for. You can also have a UTEC do it with the spare solenoid, but you said you we're going to pro-tune. I don't really recommend switching to UTEC because it can run a alky system. I want to dump my UTEC soon, and go ACCESS port.
