Any one try the boost max from jms
Just curious if any one has tried these out and have any input, they seem pretty good claiming 98whp gains and waranty safe, almost seems to good to be true!

I guess it should say it's dealer untraceable it does not write anything to the Ecu, if a waranty issue came up couldn't you just remove it bring it in and no one would no?
