I have been reading and searching I even called Quadzilla to buy one but never got a call back. It said it adjust if temps get to high? Yes, no? I am not looking for massive power. 50/160 type box adjustable from inside is preferred. Something safe if there is such a thing. Easy to remove, plug and play. I don't want to get into more than the fuel pressure gauge I now have. May be and air box but rather leave air and exhausts stock. I know looking for a miracle. I tow my race car and trailer which is 7,000 lb. and use it for work and occasionally tow 10,000 and truck loaded to gross. I would rather not have to wait when I order it. I see many boxes need to be ordered. Thanks for your help.
