I guess some of u guys were right...my driving style changed when I got my car back with motordyne exhaust lol so. I did a test if any of u remember last week I said full tank I was only gettin 305 miles I short shifted at like 2k all day today nd used cruise control in high gears. ..2 dots went out then when to gas station put 14 bucks into it and all dots were filled drove 2 miles ended up with 336! Lol shame on motordyne e370 for making me drive so hard;)
