First off for those of you who know me and for those of you that don't, I am NOT one of those guys that think every little mod gives you 20hp. Now, I live down here in fla and if you dont know, it is in the 30's where I live. I closed the restaurant tonight and on my way home I noticed a very interesting thing. I was breaking the tires loose @ 4000rpms on dry pavement in first gear.:dontknow: When I shifted into second, it felt like I was going 65mph in a few secs. I used to live in Colorado and this never happened. So I started to think, what have I done to the truck lately.??? I moved the maf sensor right behind the filter on my custom cold air intake and I changed my plugs today. I know plugs wont do this, but maybe that maf sensor is getting a truer reading on the colder air. My wideband reading was the same in second gear sooo my tune is the same.:adore: All I know is there are a few NEW tread marks in my parking lot at work and on the way home.:driver: :driver:
