Being that I'm a Grandfather of 3 beautiful girls I try to set an example of how to stay on the right side and play within the rules. Truth is, there was a time when I was a pain in soceity's ***. That was then, this is now. I told myself if I de-tuned the truck to get through Aircare, it was only a small fib. Only a small toe over the line. Remember that the truck blows away all the readings except for co at idle. Well after 2 trips to Aircare and 1hour of shop/sniffer time=$150 I sit before you with empty pockets. Like they say ...once a pain in the ***...always a pain...So when I insured the truck yesterday I paid an extra $85 and raised the gvw to 5001 kg. Bye to Aircare. If/when we shut that money-grab down I'll switch back. Did I think twice...no. Did I lose sleep...no. Will I tell my grandaughters...no. They made me do it.
