i use the cutout almost every time im in the car. this past fall i did burn up a motor and all the gears fell out of the cutout.
i was just out of the one year warranty when mine broke and it cost me $30 to have it rebuilt
you can ask the dozen or so people that were there on friday and they will tell you i gained 40 rwhp just by opening my cut.
i might consider posting my dyno sheet with the difference. again i still have to stock muffler on the car.

when i got mine 2 years ago it was only $130
my cutout was also good for a solid gain of 40rwhp on my last trip to the dyno
IPS is your local LSx shop they have done numerous head and cam installs. zo6 Eric is working with IPS and dynotune doing all LSx tunning.
these are the only people i would let touch my car.
both links are in my sig.
it's better to owe the goverment money than it is to have a refund. if they are giving you money back then you have given them an interest free loan. your goal should be to not have to pay and not get anything back.
