I dont think any CL members did this mod cuz all says its B.S....so you may not get any replies.
I'd suggest you email the ppl you bought it from for assistance.
Curious, if you feel any HP or torque gains, or Not.

If anything,
this mod would only add or subtract fuel across the rpm / maf signal...
at colder intake temperatures, the computer is programmed to give more fuel...
why? because colder air temperature = more dense o2 makeup...
more o2 + more fuel = more power....
but, with the IAT mod... you would be fooling around with the computer's
original programming...
if anything, an APEXi S-AFC or HKS AFR would be a better choice
than fooling with the IAT signal...
running too rich or running too lean... doesn't = power....
running perfect A/F ratios = power
