Has anybody tried to "piggyback" the IAT sensor using a resistor?
Some are claiming 20HP - by tricking it into reading a different air/fuel
ratio - can't remember the range
I'd just like to pick up this resistor at Radio Scrap
and I need to know which one

Don't bother, it's mostly a scam. You won't get 20hp from doing this.

thanks for the input
kind of thought so
but wanted definite feedback
get what you pay for!
