So I was on my way home from school cruising down on 840 in TN, when I see a 5th generation Sentra driving on the fast lane. I was cruising at about 85-90 and he was going at about 80-85, so I stay on the right lane and started to pass him. I wasn't in the mood of racing and stuff, but the stupid kid wanted something. While I was passing he speeds up just enough to stay side by side, and I kept on cruising... Few seconds later he started to rev up and get ahead and come back to me, It was night and I couldn't see if it was an SE-R or v-spec, but I saw an R in the back (??). I knew I would not get a chance with both of those! So next time he got ahead I gave in and droped to 4th and took off, he tried for a bit but my car was making some lenght pretty quick and he gave up. I slowed down after hiting about 123mph, and he kept on trying to reach me but I made sure I stayed ahead...
By the way, I only have a K&N air filter without the black box after the filter, and aftermarket exaust. I get an average of 30mpg cruising 80-85 and being easy on acceleratin compared to 26-27 before the K&N filter and the back box.
