I'd love to see some testing. I'd like to see different intakes tested. I'd like to see exhausts tested. I'd like to see before and after charts of the PCM tune on a stock vehicle using 87 octane most of all. You can't even GET 93 octane most places and even 91 octane is forty cents more a gallon!
I don't care for the rev limiter myself BUT has anyone ever considered that if there's a blowout on someone's low rated all terrains after the limiter's been lifted that lawyers are going to tee it high and hit it long?

I think you should leave your Hummer like it is and only go to Wally World and read Four Wheeler Magazines on the isle next to electronics and chill out. Oh and try Google for those answers!
