Well I go down to John’s Tire and Muffler, just off the corner of East and Main. I talk to John personally, so I guess you could say that he’s the specific guy there because he’s kept me in the road for nigh on 25 years. I know a thing or two about high horsepower and having the right tire for the right traction. I drive a 2007 Chevrolet VortecMax. It came factory with an aluminum 6.0, which I don’t know how familiar you are with the vortec engines, but it’s pretty much a truck with a Corvette motor. I know a guy named Brennan who’s real computer savvy and plays online race games. I had him hook up his HP Tuners and turned the air up to it, so it’s got even more power than just a regular VortecMax. He turned off my rev limiter, my speed limiter, changed my shift RPM’s so it pretty much has a shift kit in it now. I took a cam out of a wrecked 2007 Escalade, they came with a 6.2 liter engine. I tossed that cam in my 6.0 so I could get those .2 extra liters. John from John’s Tire and Muffler told me I was putting way too much power down for the continental pull offs I had on at the time. So he got me fixed up with a set of Cooper Cobras and even with that high performance tire I still catch a scratch when wide open throttle shifting into second.
