No, i just gave numbers from the booklet! I only have 455 miles on mine so far! And let me tell you, the lightning is FKING srt 10, ill tell ya that much! And I havent even got on it yet! And ive had 2 lightnings in the past! This srt 10 truck will run mid twelves all day long once pr drivers get used to and run the standard more times! I mean the noly reason the times are low 13s right now, 13;4 is the numbers from dodge, is because standards have alot more things to master, even from pro drivers! Ive seen two at my loca drags in teh 12s stock, so some magazines have bogus numbers! And that is with air intake, spare taken out and any undeeded weight, tail open! Just wait untill they start making more mods! I wonder what nitrous pases will be, or with vec chips installed to tune in! I mean honestly, it takes mucho cash to get a lightning in the twelves! Ram will do it almost bone stock! And gas is great, so says the book!
