Chris was pretty good about easing into the throttle on my runs,
He said its hard to keep it from down shifting into 2nd prime (passing gear) when you try to get a 3rd gear pull.
So he prefers to do the 4G Rams in 4th gear...as a result it doesn't read as high as some.
Most stock 4G's he's dyno'd come in at 290HP when its hot out (82ºF during my run)
Mine stumbled a bit at the start when he was trying to keep it from down shifting,
this was also just a day after I installed a new 2800 Stall Edge Torque Converter, so the TCM was still adjusting.
Chris said I really need a full custom tune to maximize the mods I've added,
and to smooth things out/ correct my A/F at lower RPMs ,
but its best that I wait a until my Headers are on.
