My mods were only intake,exhaust,tuner and tires for 75% of my runs
in my first year and a half with my 10' Ram.
The Torque Converter was the single biggest change that happened last fall, just before our track closed for the season.
The majority of my track slips, and best results from bone stock to where I am now
and every mod along the way were launching from no more than 800 rpm.
Fred nailed it, and until someone builds a faster Ram who can tell me differnent,
I trust his advice that has proven itself on my own truck.
