IAT relocate - my results
I did a lot of reading before doing this mod, and a lot of what I read was contradictory to everything else I read. A lot of people said it'd richen the a/f ratio and cost mileage. Most also said they noticed a little better throttle response off the line.
I relocated mine to the extra port in the air box about a month ago. My average mileage has gone from 12.4 to 12.9, which granted is only .5 mpg but at least it's not a loss. It does seem more responsive from a stop, but I don't run mine very hard so couldn't tell you at WOT or high rpm. I will say that it made most of my 3/4 throttle, under load pinging go away (yes I might have a plenum issue but that's another story). So far, so good, and the only thing it cost me was a pipe plug for the intake.
