On a stock truck, this is a worthwhile mod.
With a truck with say a CMR tune? forget it. I can't directly speak for what most CMR tuners do to IAT (which is what the PW "fools" ), but my SCT tunes essentially have turned readings from the IAT "off".....so in my case, the powerwire would be useless.
Theres a reason why you dont see all the really fast trucks running stuff like this.
Due to my workload, please do not PM me as I do not regularly check my PMs. Thank you :)
