I recently installed a cold air intake, magnaflow muffler with dual exits, ram air hood from www.keystonerestyling.com and superchip 2815 '87 octane' tune. after doing all this, my message center shows that my mileage is alot less than what it used to be when I had the 22's on last summer. Anybody else experience any thing like this?
