I finally went to DynoSpeed in Memphis and got the truck tuned. Numbers are 425 rwhp & 498 rwtq(SAE corrected). I was kinda expecting more but Im happy with what I got and that the truck is finally tuned. Here is the sheet:
They did 3 pulls, the first was just a test pull and does not...
I always get about 14 mpg in my Lightning and thats mostly highway miles. But of course, I never do the speed limit.:D Also, its my daily driver.
A pulley, intake, and a tune will get a Lightning in the 12's easly.
