What they're describing towards the bottom of the page is a circuit that SHOULD make it possible to run 450's plus boost pretty well. You guys should check this out!

I don't know that much about electronics... Are you saying this wouldn't work well for forced induction applications?
I think on Autospeed, they describe this as a solution to using *slightly* larger injectors.

If you're that cheap.. I've heard some of people slapping a resistor or something way ghetto like that on the map voltage line, then modofying thier fuel maps manually..
Shortyz and I discussed this once, and couldn't figure out how to dynamically change the voltage with a static resistor.. so we gave up. Maybe Joseph or George can pop in $0.02 on this..

Re:Check out this Air/Fuel hack!!!
Voltage dividers suck. If the load changes, so does the voltage division. Works great in a voltage divider bias circuit as it plays off a transistor, but in and of itself it's a joke of an idea.
Used to tweak the output of the MAP sensor, it would do OK as filetofit/Chris has proven on HT... the ECU itself is fixed load, so you can dial in th correct division. If you think it's an idea you can apply widely you need to pick up a book on basic electronics and learn basic ohms/kirchoff's law.
